early_postglacial
The early_postglacial data layer is part of a comprehensive study to produce a statewide digital map of the surficial geology at 1:24,000 scale. This compilation of surficial geologic materials defines the boundaries between glacial till, glacial stratified deposits, and overlying postglacial deposits. The early_postglacial layer shows areas of alluvial fan deposits, stream-terrace deposits, inland dune deposits, and talus deposits for a twenty-four-quadrangle area in west-central Massachusetts. This data layer should be used in conjunction with the underlying till_bedrock and stratified_deposits data layers, and the overlying the postglacial data layer.
The purpose of this study is to provide fundamental geologic data for the evaluation of natural resources, hazards, and land information within the Commonwealth of Massachusetts. The early_postglacial deposits data layer is part of a comprehensive effort to produce a statewide digital map of the surficial geology at 1:24,000 scale. This compilation of surficial geologic materials defines the boundaries between glacial till, glacial stratified deposits, and overlying postglacial deposits. The early_postglacial layer shows areas of alluvial fan deposits, stream-terrace deposits, inland dune deposits, and talus deposits for a twenty-four-quadrangle area in west-central Massachusetts. This data layer should be used in conjunction with the underlying till_bedrock and stratified_deposits data layers, and the overlying the postglacial data layer.
This map of twenty-four quadrangles revises previous digital surficial geologic maps (Stone and others, 1993; MassGIS, 1999) that were compiled on base maps at regional scales of 1:250,000.

Multiple agencies and individuals contributed to this data layer: MassGIS scanned and georeferenced paper copies of the published surficial geologic maps for fifteen quadrangles; the Office of the Massachusetts State Geologist vectorized the georeferenced images and compiled geologic units in order to digitally retain the original information on the published maps (Mabee and others, 2004); U.S. Geological Survey personnel compiled and digitized the basic units for nine unpublished quadrangles from scanned field maps, and then joined and edge-matched the twenty four quadrangles in order to form a seamless geologic map.

Attributes have been visually checked by the compilers.
Polygon features conform to the following topological rules. There are no duplicate polygons. Polygons do not self overlap. No automated procedures or tests were performed to guarantee desired topology other than visual inspection.
The completeness of the data reflects the feature content of the basic units chosen for this interim product for all data sources. Additional information can be found on the data sources, which may be utilized in future compilations. The layer is complete in the sense that it accurately reflects the early postglacial units for this twenty-four-quadrangle area, noting that edits (including additional units) may occur to this data set when it is edge-matched to surrounding quadrangles during future compilations.
The horizontal positional accuracy of these data complies with the United States National Map Accuracy Standards for 1:24,000-scale maps. According to this standard, not more than 10 percent of the locations tested are to be in error by more than 1/50 inch (40 feet) measured on the publication scale of a USGS 7.5-minute topographic quadrangle map.

The Office of the Massachusetts State Geologist vectorized the georeferenced images in order to digitally retain the original line work of the published maps (Mabee and others, 2004). Digital geologic map units were compiled and grouped into basic units and attributed: artificial fill, swamp deposits, floodplain alluvial deposits, stream terrace deposits, glacial stratified deposits, glacial till, and bedrock areas (outcrops and areas of shallow bedrock).

alluvial-fan deposits
Generally coarse gravel and sand deposits on steep slopes where high-gradient streams entered lower-gradient valleys. Some alluvial fans in this area were graded to lowering levels of glacial Lake Hitchcock. Some fans continue to form today
compiler
stream-terrace deposits
Sand, gravel, and silt deposited by meteoric water (locally distal meltwater) on terraces cut into glacial meltwater sediments along rivers and streams. Most stream-terrace deposits are less than 10 ft thick and overlie thicker glacial deposits; textures are usually similar to underlying glacial meltwater deposits. Many stream terraces in the Connecticut River valley are composed of fine to medium sand and overlie lake-bottom silt and clay
compiler
inland-dune deposits
Fine to medium, well-sorted sand in transverse, parabolic, and hummocky dunes as much as 60 ft thick. Deposits occur chiefly in the glacial Lake Hitchcock basin where sand derived from extensive glacial-lake deltas that were not yet vegetated was deposited in dune forms by early postglacial winds. Dune sand is now fixed by vegetation except where disturbed by human activities
compiler
talus deposits
Angular, loose blocks of basalt and diabase accumulated by rockfall and creep at the base of bedrock cliffs along linear traprock ridges in the Mesozoic lowland. Talus deposits form steep, unstable slopes. Generally less than 20 ft thick
