DESCRIPTION OF MAP UNITS Holocene Deposits Artificial Fill. Artificially-emplaced earth along road beds, embankments and in low-lying areas. Graded or Filled. Area of extensive artificial excavation or filling. Alluvium. Silt, sand, and gravel deposited by modern streams. Deposits include stream channel and bar deposits and finer-grained floodplain deposits. Wetland deposits are common within these areas and are not distinguished. Thickness in the tributaries is typically less than 3 meters, although the depth may be much greater in the valleys of the larger streams. Wetland Deposits. Accumulations of clastic sediment and/or organic matter. Commonly overlaying other sediments such as alluvium, lacustrine deposits, or till. Only a few of the larger deposits are shown. Wetland Deposits, Peat or Muck. Thick accumulation of organic matter with minor clastic sediment. Commonly overlaying other sediments such as alluvium, lacustrine deposits, or till. Thickness of organic horizon ranges from 0.3 meter to greater than one meter. Stream Terrace Deposits. Silt, sand, pebble, cobble, and boulder gravel deposited on terraces above the modern floodplains of streams. They represent former floodplains that have been dissected by younger streams. Talus. Fans or aprons of fallen rock at the base of cliffs. May contain colluvial (slope-wash) deposits as well. Of variable thickness. Colluvium. Fans or aprons of sediment at the base of steep slope segments. Slope-wash deposits of variable thickness. Pleistocene Deposits Lake Deposits, undifferentiated. Coarse- to fine-grained lake deposits. Largely deposited in arms of glacial Lake Winooski, excerpt in the northern part of the study area to the east of Hardwick village, where the deposits may grade to a higher-level glacial lake. Lake Deposits, Coarse-grained. Well-sorted sand, pebbly sand and/or sandy gravel deposited in shoreline, shallow waters, or lake bottom environments of glacial Lake Winooski or in higher-level glacial lakes of limited areal extent. Parts of the coarse-grained deposits between Lower Cabot and Cabot in the Winooski River valley and in the lower Jug Brook valley may be delta or shoreline deposits, but more detailed mapping would be needed to distinguish these. Lake Deposits, Fine-grained. Clay, silt, and very fine to fine sand deposited in deeper waters. Commonly varved. Deposited in lake bottom environments of glacial Lake Winooski or in higher-level glacial lakes of limited areal extent. Ice-contact Deposits. Unsorted to poorly-sorted sand, gravel, and silt deposited in contact with glacial ice. Kettle holes and a small esker are visible on the ice-contact deposits north of Nichols Pond. A probable esker buried by collapsed lacustrine sands and silts is exposed in the sandpit west of Smith Corner in Walden. Till. Dense to very dense, unsorted to very poorly sorted, fine-sand- to silt-matrix till. Surface boulders are common, with boulders of the local Woodbury Granite common in the western third of the study area. Thickness of the till is highly variable, from less than 3 meters to greater than 30 meters. Till, Thin. Descriptions as in preceding unit. Thickness highly variable but generally less than 3 meters and bedrock outcrops are very common. Bedrock. Area of extensive bedrock exposures. Most outcrops visited during this study are indicated by the point symbols described below.

EXPLANATION This plate shows locations of water wells in and near the quadrangle. As many of the older wells have uncertain locations, only wells with verified locations are used in this analysis. Newer wells with driller-reported GPS locations or E911 addresses are assumed to be close to the correct locations. Other well locations have been verified by use of State records of hazardous waste sites and septic systems, searches of town records, local knowledge, or online searches to verify that the listed owner has a residence at the location shown.

EXPLANATION This plate shows depth to bedrock in feet. Depth to bedrock is indicated by the size of the green symbols at each well location. Bedrock outcrops are shown as black dots. The red lines are approximate contours at depths of 20, 40, 60, 80, and 100 feet. Note that most of the areas with more than 20 feet to bedrock are in Hardwick and Walden. The depth is more certain in areas with abundant water well logs and/or bedrock outcrops and less certain in areas where this information is sparse. The mean depth to bedrock in the wells is 32.1 feet and the median value is 20.5 feet.
