Strickland The following is a brief description of soil conditions as they relate to the above referenced subdivision. After breakup and the frost leaves the ground more test holes will be taken for a better overall picture of the subsurface as it pertains to drainage and percolation. The subdivision lies within "... sorted and unsorted drift of the Nap- towne glaciation ..." which formed" deposits of advance outwash, lateral and ground morraines, pitted ~wash, and ice contacts of sand and gravel ... advanve of the Wisconsin age ..." (Dobrovolny and Miller, 19 9). Actual field information was derived from two visual sources: 1/ open road out along north property line. 2/ existing road cuts for access road through property to the north. Both sources show an organic/silt overburden of 12" to 24" in depth under- lain by morraine and outwash deposits of glacial till consisting of sandy gravel, gravel, and gravelly silt. Test hole depths of all'revealed no change in the till strata. Permafrost conditions are not known to exist within the confines of the subdivision.

Dear M~. Strickland The followingis a brief description of soil conditions as they relate to the above referenced subdivision, More detailed phy- siographic analysis can be obtained in Geologic Sumvey Bulletin 1093, "Sumficial Geology of Anchorage and Vicinity Alaska" by Dobrovolny and Miller, and Geologic Map of Alaska by Dutro and Payne. Actual field information was derived from four visual sources and located as shown on the acc~mpaningmap. Test hOles 1 & 2 revealed mostly sand and silty sand with some 4" to 6" stones whereas test holes 3 and 4 had a good mixture of sand and gravel. Ail four sources show an organic/silt overburden of 6" to 18" in depth underlainby'morraine and outwash deposits of g~acial till consisting of sand, sandy gravel and silty sand. Permafrost conditions are not known to exist within the confines of the subdivision. As the lower half of this subdivision has already been approved by youm department we are requesting approval at this time for the upper or Eastern half of the subdivision, SHould you require add- itional information, please do not hesitate to contact me.

Schmoll, Ernest Dobrovolny and Chester Explanation of Geologic Units and Summary of Ground-Water pOtential Physical Character Ground-Water Potential Gravel and sand, commonly quite coarse-grained, with small amounts of silt; deposited by larger streams as alluvial* fans at the mountain front. Sand and gravel, with silt and clay; deposited as stream'alluvium in channels and on terraces, flood- plains and small alluvial fans. Sand and gravel, with some silt, clay and diamicton**; deposited chiefly as ice contact features***. Silt, with some clay and fine- grained sand; deposited in an estuarine (tide-affected) environ- ment. Clay and silt, generally overlain by peat, includes some fine-grained sand and marl (limey clay); pond deposits. Clay and silt with some sand; glacial lake deposit Diamicton and gravel with minor mixed gravel, sand and silt; here grouped as S__o_~nger moraine-- mater~al depo~-]-~6~-~-{]~ by direct glacial action. Good water-bearing unit; may yield large quantities of water to wells. Known yields up to 300 gpm(gallons per minute) on alluvial fan of Meadow Creek, but often yields are only lO-15 gpm. The fan of Peters Creek is virtu- ally unexplored for ground-water potential. May yield moderate quantities of ~ater to wells--known yields of 5 to 50 gpm. 'May yield small quantities of water to wells,-known yields from 1 to 10 gpm. Not a water.-bearing unit. Not a water-bearing unit. Not a water-bearing unit. May yield small to moderate quantities water locally in gravelly or sandy lenses. Available data from areas south and east Of Eagle River townsite show average yields of about l0 gpm, although two wells have reported yields of 30 and 45 gpm respectively. Diamicton, with minor amounts of gravel, Sand,~silt and clay; here grouped as older moraine-- includes Pond d~posits in lowland areas, boulders on up]and sur- faces. Contains more fine mat- erials than Y. Rubble [large, angular rock fra§- ments] on steeper slopes, and mixed gravels,.sands and silts.; colluvium and minor.alluvium Rubble and diamicton; landslide deposit. BEDROCK Sedh~entary rocks, chiefly silt- stone, sandstone and coal. Met~aorphic rocks, chiefly metasand- stone typos. Also inc!udos Chert, greenstone, chef by argi] lite, argil- lite, greenschist, gm~.iss, metr:~- gabbro, and ~cta-dioritc, as well as some sm~ll intrusive bodies of felsic' to intermediate hy~abyssal rochs.
