FROM: Laura Carstens, Planning Services Manager
SUBJECT: Shot Tower Archeological Investigation -Amended Contract
INTRODUCTION
The purpose of this memo is to transmit for City Council review and approval the Great
Lakes Archeological Research Center Amended Contract for additional services
associated with the Shot Tower Archeological Investigation.
DISCUSSION
The City has committed $200,000 for the rehabilitation and interpretation of the Shot
Tower as part of the Americas River project at the Port of Dubuque. In 2005, the City
received a $15,500 Hisforic Resource Development Program grant from the State
Historical Society of Iowa (SHSI) for the archeological survey required by the National
Park Service (NPS). During the archeological investigation, the archeologist and Loras
College students excavated the southeast corner of the Shot Tower. They uncovered a
portion of the historic Shot Tower well and the well was found to be in good condition.
City, NPS, and SHSI Staff met to discuss the findings and agreed the well should be
exposed and incorporated into the final Shot Tower design and experience.
On February 20, 2006, the City Council approved the issuance of a Request for
Proposals for the Shot Tower Archeological Survey which was budgeted to cost
$30,000. On March 13, 2006, the Consultant Selection Committee met and
recommended selecting Great Lakes Archeological Research Center (GLARC) to
perform the archeological survey. To date, compensation for the work performed by
GLARC is $14,315.47. The additional work to be performed by GLARC is outside the
scope of the initial contract and State requirements for the completion of the Shot Tower
Archeological Investigation.
The new contract, which will allow for the excavation of the remainder of the fill to
expose the Shot Tower well, varies based on Loras Student participation. If Loras
students are not available to assist with the excavation, the compensation to GLARC will
be $14,172.48. If Students are available, compensation will be $11,432.02. The City is
currently working with Loras College to determine whether Loras students will be able to
participate in the Shot Tower Excavation. Compensation for either scenario will be
under the approved $30,000 budget.
RECOMMENDATION
I recommend that the City Council approve the enclosed amended contract and
authorize the Mayor to sign the enclosed contract to allow for the additional excavation
of the interior of the Shot Tower with compensation not to exceed $14,172.48.

Archaeological Data Recovery Plan for the
Excavation of Deposits Filling the
Interior of the George W. Rogers Company
Shot Tower (13DB838) in the City of Dubuque, Iowa
Introduction
The following archaeological data recovery plan is intended to guide the excavation of
remaining fill deposits within the George W. Rogers Company Shot Tower (13DB838),
also known as the Dubuque Shot Tower, located in the City of Dubuque, Iowa, and is
based upon archaeological and geomorphological investigations performed by Great
Lakes Archaeological Research Center, Inc., and Strata Morph Geoexploration, Inc. as a
component of the Shot Tower Rehabilitation Project. The rehabilitation project is
sponsored by City of Dubuque (City), which is receiving funding through a Historic Sites
Preservation grant (No. 04-007) and a Historic Resource Development Program grant
(No. 06-022) awarded by the State Historical Society of Iowa, and a Save America's
Treasures grant (No. 19-04-ML-0110) awarded by the National Park Service. Prior
archaeological and geomorphological investigations conducted as part of the
rehabilitation project attempted to determine how much of the Shot Tower base is buried
below the present ground surface and the accuracy of the 1934 Historic American
Buildings Survey (HAWS) sketches depicting the structure's interior foundation features.
Of the two goals, only that related to the accuracy of the 1934 HAWS sketches, and the
data that support it, is pertinent to the current data recovery plan. After the relevant data
are briefly reviewed in the following paragraphs, the data recovery plan developed for the
excavation of the remaining fill deposits within the Shot Tower (12DB838) is presented.
Prior ArchaeologicaUGeomorphological Investigations
The archaeological and geomorphological investigation of the Shot Tower interior, which
measures approximately 14 feet square, began with the manual extraction of three soil
cores followed by the excavation of a 5 feet square (ft sq) unit filling the structure's
southeastern comer. Investigators extracted the three soil cores using an Oakfield soil
probe with extensions. Probe No. 1 sampled the southwestern corner of the tower, while
Probe No. 2 sampled the southeastern comer, and Probe No. 3 recovered deposits from
the center of the structure. Each probe extended to varying depths; however, all revealed
a uniform stratigraphic sequence consisting of gravel fill over sand resting on a rubble
layer on top of a homogenous sandy layer. The sandy layer represents dredge spoil that
similarly occurs outside and surrounding the Shot Tower base. Probe Nos. 1 and 2
extended 6.8 ft and 5.7 ft respectively below the ground surface (bgs), while Probe No. 3
continued down approximately 10.6 ft bgs before ending at the presumed top of a brick
rubble deposit. This deposit is interpreted as material that collected in the center of the
structure, possibly in the shot catchment welUtub/reservoir, sometime after the 1911 fire
that resulted in the commercial abandonment of the Shot Tower. In contrast, Probe No. 1
ended in the sandy dredge spoil whereas Probe No. 2 was thought to have encountered a
structural surface, possibly a floor that prevented it from being pushed deeper.
As a result of the depth of the fill and the potential presence of a structural surface
revealed by Probe No. 2, together with a desire to be able to relate subsurface deposits
by 0.42 ft wide. Discrepancies between the two sets of measurements where comparable
data are known, is due to variations of widths and heights, which the two sets of recorders
capture in their reported measurements, along a tier. Complete exposure of the interior of
the Shot Tower will reveal how uniform each tier is regarding its height and width.
Suffice it to state at this time, the HABS recorders observed a portion, if not the entire
interior base of the tower.
Near Future Archaeological Investigations
Upon realizing that the HABS drawing depicting the interior side of the foundation is at
least in part accurate, and recognizing that the restoration and interpretation of the Shot
Tower will be enhanced by exposing the lower structural features, the City consulted with
the Iowa State Historic Preservation Office and the National Park Service about the
archaeological excavation of the remaining interior fill. Consultation was required in
order to determine if the removal of the remaining interior fill would have an adverse
affect upon the structure's stability and remaining interior archaeological deposits. As a
result of this consultation, an archaeological data recovery document was created in order
to guide the excavation of the remaining fill from within the Shot Tower. The data
recovery plan, which is presented in greater detail in the following sections, consists of
five broadly defined tasks: excavation (Task 1), documentation (Task 2), laboratory
analysis and data organization/interpretation (Task 3), report preparation (Task 4), and
transfer of artifacts and documentary records to a curation facility (Task 5).
Data Recovery Plan
Task 1: Excavation
The interior of the Shot Tower measures approximately 14 ft sq and encompasses
approximately 196 square feet (sq ft) of which 25 sq ft have been partially excavated,
mapped, profiled, and photographed. In order to maintain consistency in the excavation
and documentation of the southeastern corner of the Shot Tower, the interior of the tower
will be divided into uneven quarters, and each quarter will be excavated as a separate unit
for purposes of spatial control. The northern edge of the existing southeastern unit (Unit
1) will be extended westward while the western one will be extended northward to create
the four quarters: the southeastern quarter (Unit 1) will measure 5 ft by 5 ft, the
southwestern quarter (Unit 2) will measure 9 ft east-west by 5 ftnorth-south, the
northwestern quarter (Unit 3) will measure 9 ft sq, and the northeastern quarter (Unit 4)
will measure 9 ft north-south by 5 ft east-west. Generally, fill removed from each unit
will not be screened; however, exceptions will be made for the fill excavated from the
upper surfaces of additional floor supports, which are expected to be exposed in each
corner, or contacting the lower surface of the foundation. Similarly, deposits removed
from the shot catchment well/tub/reservoir will be screened. In addition, soil samples will
be collected from the fill contacting the lower foundation surface and that from within the
shot catchment well/tub/reservoir in order to measure levels of residual hazardous by-
products of historical lead shot production.
Excavation of the four units will follow a patterned schedule in order to extend existing
Unit 1 wall profiles the length of the north and west dimensions of the Shot Tower's
interior. Fill will be removed from Units 2, 3, and 4 in 3-to-4 ft intervals; however, finer
records generated by the study will be transferred to the National Mississippi River
Museum and Aquarium or another designated facility in Iowa for curation and archival
purposes (also see Task 3).
Transferal of project related materials for curation and archival purposes will mark the
end of the proposed archaeological project investigating the Shot Tower's interior fill
deposits.

data that support it, is pertinent to the current data recovery plan. After the relevant data
are briefly reviewed in the following paragraphs, the data recovery plan developed for the
excavation of the remaining fill deposits within the Shot Tower (12DB838) is presented.
Prior ArchaeologicaUGeomorphological Investigations
The archaeological and geomorphological investigation of the Shot Tower interior, which
measures approximately 14 feet square, began with the manual extraction of three soil
cores followed by the excavation of a 5 feet square (ft sq) unit filling the structure's
southeastern corner. Investigators extracted the three soil cores using an Oakfield soil
probe with extensions. Probe No. 1 sampled the southwestern corner of the tower, while
Probe No. 2 sampled the southeastern corner, and Probe No. 3 recovered deposits from
the center of the structure. Each probe extended to varying depths; however, all revealed
a uniform stratigraphic sequence consisting of gravel fill over sand resting on a rubble
layer on top of a homogenous sandy layer. The sandy layer represents dredge spoil that
similarly occurs outside and surrounding the Shot Tower base. Probe Nos. 1 and 2
extended 6.8 ft and 5.7 ft respectively below the ground surface (bgs), while Probe No. 3
continued down approximately 10.6 ft bgs before ending at the presumed top of a brick
rubble deposit. This deposit is interpreted as material that collected in the center of the
structure, possibly in the shot catchment welUtub/reservoir, sometime after the 1911 fire
that resulted in the commercial abandonment of the Shot Tower. In contrast, Probe No. 1
ended in the sandy dredge spoil whereas Probe No. 2 was thought to have encountered a
structural surface, possibly a floor that prevented it from being pushed deeper.
As a result of the depth of the fill and the potential presence of a structural surface
revealed by Probe No. 2, together with a desire to be able to relate subsurface deposits
and structural features to the Shot Tower walls, investigators excavated the 5 ft sq unit
adjoining the southern and eastern walls of the tower's southeastern corner. The unit's
size insured that it overlapped the current, concrete sills of the lower window openings
present on the eastern and southern sides of the structure. Fill excavated from the unit
was screened through one-quarter inch hardware mesh cloth, and artifacts were collected
and bagged by provenience.
Excavation of the unit encountered the previously described gravel fill over sand resting
upon rubble fill on top of the sandy dredge spoil sequence, and exposed structural
features before being terminated at a maximum depth of approximately 8 ft bgs. The
excavation was terminated at 8 ft due to concern for the safety of excavators. Artifacts
were collected from the rubble layer, which is interpreted as the circa 1960 ground
surface where debris related to the early 1960s effort to stabilize the Shot Tower
collected. Prior to circa 1960, the surface probably represented the top of the sandy
dredge spoil deposited across the area in order to raise the ground above flood water level
for economic development during the early 1940s. While the soil probes suggested the
sandy dredge spoil to be homogenous, excavation of the unit revealed clay clasts and
strata occur between sandy strata, and it is one of the stiff clay deposits, and not a
structural feature, that prevented Probe No. 2 from penetrating deeper into the deposits.
The dredge spoil deposits yielded several clam shells, but no other artifacts.
Structural Features
Structural features related to the foundation and lower flooring of the Shot Tower began
appearing approximately 4.0 ft bgs. The first feature exposed is a roughly triangular
arrangement of cemented rocks, which subsequently has been shown to be resting on a
foundation comprised of at least three stepped tiers. Several pieces of flat glass and the
articulated shoulder bones, which show butcher (saw) marks, of a large mammal rested
on or between the rocks. In addition, flecks of charcoal are present between the rocks and
no doubt represent trapped debris from the 1911 fire. The upper surface of the rock
arrangement is roughly even in elevation with an approximately 2 inch wide rock ledge
protruding from and running the exposed length of the tower's southern wall. Both the
rock arrangement and ledge are tentatively interpreted as supports for a lower wooden
floor, which probably once encircled the shot catchment welUtub/reservoir that existed in
the central, lower portion of the foundation. Neither support feature is depicted on the
1934 HABS scaled drawings; however, the tiered foundation is shown.
The HABS drawing shows the interior side of the foundation defined by three stepped,
tiers. Excavation of the unit to a depth of 8 ft exposed three tiers, and a hand probe
extended approximately 1.5 ft deeper suggests another depicted surface---the possible
floor--exists. The surface of the upper tier begins approximately 4.8 ft bgs and has a
curved edge that extends 1.4-to-2.25 ft from the wall before dropping 1.5-to-1.9 ft to the
top of the second tier, which has a curved edge and is approximately 0.42 ft wide. The
top of the second tier rises 0.75-to-1.2 ft above the third tier, which measures
approximately 0.42 ft wide and is similarly curved. On the HABS drawing, the first tier is
shown as 1.7 ft high and 0.67 ft wide at its narrowest, while the second tier is described
as 1.0 ft high by 0.5 ft wide, and measurements for the third tier are given as 1.6 ft high
by 0.42 ft wide. Discrepancies between the two sets of measurements where comparable
data are known, is due to variations of widths and heights, which the two sets of recorders
capture in their reported measurements, along a tier. Complete exposure of the interior of
the Shot Tower will reveal how uniform each tier is regarding its height and width.
Suffice it to state at this time, the HABS recorders observed a portion, if not the entire
interior base of the tower.
Near Future Archaeological Investigations
Upon realizing that the HABS drawing depicting the interior side of the foundation is at
least in part accurate, and recognizing that the restoration and interpretation of the Shot

to guide the excavation of the remaining fill from within the Shot Tower. The data
recovery plan, which is presented in greater detail in the following sections, consists of
five broadly defined tasks: excavation (Task 1), documentation (Task 2), laboratory
analysis and data organization/interpretation (Task 3), report preparation (Task 4), and
transfer of artifacts and documentary records to a curation facility (Task 5).
Data Recovery Plan
Task l: Excavation
The interior of the Shot Tower measures approximately 14 ft sq and encompasses
approximately 196 square feet (sq ft) of which 25 sq ft have been partially excavated,
mapped, profiled, and photographed. In order to maintain consistency in the excavation
and documentation of the southeastern corner of the Shot Tower, the interior of the tower
will be divided into uneven quarters, and each quarter will be excavated as a separate unit
for purposes of spatial control. The northern edge of the existing southeastern unit (Unit
1) will be extended westward while the western one will be extended northward to create
the four quarters: the southeastern quarter (Unit 1) will measure 5 ft by 5 ft, the
southwestern quarter (Unit 2) will measure 9 ft east-west by 5 ftnorth-south, the
northwestern quarter (Unit 3) will measure 9 ft sq, and the northeastern quarter (Unit 4)
will measure 9 ft north-south by 5 ft east-west. Generally, fill removed from each unit
will not be screened; however, exceptions will be made for the fill excavated from the
upper surfaces of additional floor supports, which are expected to be exposed in each
corner, or contacting the lower surface of the foundation. Similarly, deposits removed

be collected from the fill contacting the lower foundation surface and that from within the
shot catchment welUtub/reservoir in order to measure levels of residual hazardous by-
products of historical lead shot production.
Excavation of the four units will follow a patterned schedule in order to extend existing
Unit 1 wall profiles the length of the north and west dimensions of the Shot Tower's
interior. Fill will be removed from Units 2, 3, and 4 in 3-to-4 ft intervals; however, finer
grained intervals may be used if stratigraphic or artifactual conditions require them. The
excavation of a set amount of fill will first take place at Units 2 and 4 in order to extend
the north and west wall profiles of Unit 1 for documentation purposes. Afterward, a
similar amount of fill will be removed from Unit 3, and then the cycle of fill removal will
be repeated; however, after 6-to-7 ft of fill has been removed from Units 2, 3, and 4,
additional fill will not be removed from Unit 3, which fronts the current doorway leading
into/out of the structure, until Units 1, 2, and 4 are excavated to their bases. Leaving the
removal of the lower fill of Unit 3 until the end will permit easier access to and exit from
the lower excavated levels of Units 1, 2, and 4; and serve as a platform that supports
equipment facilitating the mechanical removal of excavated fill. Excavation of the last
unit will complete the interior excavation of fill from the Shot Tower, and the excavated
area will not be backfilled.
Task 2: Documentation
During the archaeological investigation of the Shot Tower's interior, excavators will
document the field work with field notes, data logs, plan maps, wall profiles, and
photographs. Within each unit, all features will be documented graphically with
photographs and line drawings. Upon completion of the excavation, a plan view of the
interior base of the Shot Tower will be drafted showing all exposed structural features
and their relationship to one another. At the end of the field investigation, all excavation
documentation, together with any recovered artifacts, will be removed to a designated
laboratory and office facility where the records and raw data will be processed, analyzed,
and interpreted.
Task 3: Laboratory Analysis and Data Organization/Interpretation
Materials removed to the designated laboratory and office facility will be organized,
reviewed, and prepared for incorporation into the project's final report. Collected artifacts
will be inventoried, sorted, washed, labeled, analyzed, and interpreted. In addition,
artifacts will be prepared for curation according to the procedures outlined by the facility,
either the National Mississippi River Museum and Aquarium or another approved
repository in Iowa, that will receive them. Photographic film will be processed and photo
logs reviewed. In addition, field notes, line drawings and maps, and soil profiles will be
reviewed or prepared for presentation in the final report. Soil samples collected in order
to measure lead contamination within the Shot Tower, will be turned over to the Iowa
Department of Natural Resources for processing and analysis.
Task 4: Report Preparation
A final report detailing the techniques and methodologies, as well as the results of the
study will be prepared according to the Department of the Interior's Format Standards for
Final Reports of Data Recovery Program and submitted to the City of Dubuque for
review and distribution to the National Park Service and the Iowa State Historic
Preservation Office for further comment and approval.
Task 5: curation and Archiving Artifacts and Documentary Records
Upon acceptance of the final report by the City of the Dubuque, the National Park
Service, and the Iowa State Historic Preservation Office, all artifacts and documentary
records generated by the study will be transferred to the National Mississippi River
Museum and Aquarium or another designated facility in Iowa for curation and archival
purposes (also see Task 3).
Transferal of project related materials for curation and archival purposes will mark the
end of the proposed archaeological project investigating the Shot Tower's interior fill
deposits.
