1.2 DESCRIPTION
1.2.1 ABSTRACT:
1. IDENTIFICATION
This coverage depicts areas believed to possess a high archaeologic potential. It
was developed by the Illinois Sate Museum and is intended for coarse regional
analysis. The nominal map scale is 1:500,000 with a positional National Map
Accuracy Standard value of 832 feet. Note however that the nature of the
boundaries themselves, approximate limits of archaeologic potential, make specific
statements of positional accuracy unimportant.
Background - The Illinois State Agency Historic Preservation Act (P.A. 86-707)
mandates state government to preserve, restore, and maintain the historic
resources of the state. Activities that can result in change of historic properties
undertaken, supported or administered by a State agency are subject to review by
the Illinois Historic Preservation Agency (IHPA). The IHPA also regulates private
undertakings which require a permit from a State agency. Private undertakings
that will affect a documented archaeological site or an area with a high potential
for archaeological resources, must inventory and assess the scientific and historic
potential of archaeological and historic properties within the project area. The
Illinois State Museum (ISM) is responsible for preparing maps illustrating areas
with a high probability for archaeological resources.
Based on the statewide distribution of documented archaeological resources, a
high probability area "means any occurrence of Cahokia Alluvium, Carmi Member
of Equality Formation, Grayslake Peat, Parkland Sand, Peyton Colluvium the
Batavia Member of the Henry Formation, or the Mackinaw Member, as mapped
by Lineback et al. (1979) at a scale of 1:5000,000 within permanent stream
floodplains and including: 1) 500 yards of the adjoining bluffline crest of the Fox,
Illinois, Kankakee, Kaskaskia, Mississippi, Ohio, Rock, and Wabash Rivers and
300 yards of the adjoining bluffline crest of all other rivers or 2) a 500 yard wide
area along the shore of Lake Michigan abutting the high water mark."
The Archaeological Resource Potential map is a combination of administrative,
geology, and hydrology GIS data sets. The county boundaries of Illinois (ILLIMAP
- A computer-Based Mapping System for Illinois, D.H. Swann, P.B. DuMontelle,
R.F. Mast, L.H. Van Dyke; Illinois State Geological Survey Circular 451; 1970; 24
pages) serves as a base map. All processing was done at the county level. The
geological information is from Quaternary Deposits of Illinois (Lineback, J.A. 1979,
scale 1:500,000). ISM staff redigitized all of the quaternary deposits specified by
the law. Hydrology information is derived from the USGS 1:100,000 DLG files
(Standards for Digital Line Graphs, 1987, USGS).
The coverage, a map of each county, contains polygons with a single attribute
called HIGHPROB. A value of 1 indicates an area of "high archaeological resource
potential"
The steps taken in deriving the boundaries of high potential areas are as follows.
1) The extent of the seven quaternary deposits mentioned above were
hand-digitized by ISM personnel from Lineback (1979) from county size tiles that
had been photo enlarged to 200 percent, making as effective digitizing scale of
1:250,000.
2) Hydrology was clipped fro the 1:100,000 USGS DLG data and permanent
streams, wide streams, and shorelines were extracted. All ponds were then
removed to produce a simple line coverage.
3) The boundaries of Cahokia Alluvium were used to simulate the bluff edge.
4) Those portions of Cahokia Alluvium associated with one of the 8 large rivers
mentioned in the bill were extracted
5) The Cahokian Alluvium was buffered by 500 meters near the big rivers and
300 meters elsewhere.
6 ) A buffer of 300 yards was produced around all permanent streams not
associated with Cahokia Alluvium on the Lineback map.
7) A small amount of edgematching was done at county boundaries, although
some discrepancies still exist.
1.2.2 PURPOSE: To determine the probability of a high achaelogical resource area.

1.4 STATUS
1.4.1 PROGRESS: Complete. Data set is complete in that the entire state is
included. However, this map is a model of archaeological resource potential, not a
map of a tangible resource with known boundaries. Clearly some areas with
resource potential are not included, rather this maps reflects the definition
prescribed by law.
