J <br /> <br />J <br />J <br />J <br />II <br />11 <br />J <br />! <br />11 <br />! <br />I <br /> <br />I <br /> <br />The project area is located approximately 1 to 1% miles north of <br />the MissiSsippi River and 3/4 to 2 miles west of the Rum River, <br />on level ~o gently rolling uplands that incorporate parts of two <br />geomorphi~ regions: the Mississippi Valley Outwash area (western <br />portion df project route) and the Anoka Sand Plain (eastern <br />portion of same). Both areas owe their geomorphological <br />characteristics to processes that occurred during the later <br />stages of the Wisconsin glaciation. Low areas are marsh), - <br />isolated ~epressions as well as larger wetlands that are linked <br />by poorly, developed drainages. Uplands feature well drained <br />sandy soils over a substratum of sand and/or gravel -- along the <br />project ~oute primarily Nymore and Hubbard sands (USDA Soil <br />Conservation Service 1977; University of Minnesota !980). <br /> <br />Pollen cores from the region suggest that it was rather dry for <br />much of : the postglacial period, with a predominance of <br />grassland~ and dry oak woods (Harrison 1978). At the time of <br />initial ~uro-American settlement, oak openings and barrens <br />predominated on the uplands, while narrow belts of river bottom <br />forest was ~ound along the Rum and Mississippi Rivers (Marschner <br />1974). <br /> <br />While a number of archaeological sites have been identified in <br />the northern, central and ~astern parts of Anoka County <br />(Harrison !978), the western portion is still relatively poorly <br />known in this respect -- mainly, we can assume, because of the <br />lack of c~mprehensive archaeological survey in this area rather <br />than actual lack of such evidence. So far, only one Native <br />American ~ite has been recorded close...to the survey area: 21 AN <br />6, a group of more than a dozen mounds described in the late <br />1800s as~ located on the northwestern shore of Round Lake. <br />Another D~ssible site, 2! AN 101, yielded a concentration of <br />bison bones from a marsh located between the southeastern shore <br />of Round Lake and the Coon Creek drainage, However, there were <br />no artifacts in association that could link the bones, in a <br />positive ~anner, with early Native American cultural activity. A <br />few sites have also been recorded to the southwest, on the <br />Hennepin County side of the Mississippi River: 21 HE S5, a <br />single mound, and 21 HE ~9, a group of .16 mounds, both sites <br />near Cha~plin, as well as 21 HE 88, a group of 23 mounds <br />overlooking Elm Creek near its confluence with the Mississippi. <br />Although ~here is no evidence on record, as yet, of habitation <br />sites in ~his area, the presence of burial sites, as well as the <br />~opograph~c configuration of well drained uplands along lakes <br />and major~ waterways like the Mississippi and Rum Rivers, would <br />suggest that a number of such sites dq.exist. <br /> <br />3.0 SURVEY PROCEDURE AND RESULTS <br /> <br />Although the proposed alignment is 80 ft wide, survey coverage <br />was widened to encompass approximately 150 ft. The corridor was <br />walked along transects spaced at 10 meter intervals. The <br />following descriptions are keyed to survey segments on Figure 1. <br /> <br /> <br />
