This map covers the westernmost counties of the State, providing a current look at how bedrock units and major surface deposits are distributed. The map was developed by David K. Brezinski and Robert D. Conkwright, Jr.</div><div style="font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;"><br /></div><div style="font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;">As residential, commercial and recreational development increases in the western portion of the State, and with the potential for the Marcellus Shale to serve as a natural gas resource, the updated map will provide necessary information on the geologic factors that affect and guide decisions about the wise use of the landscape and natural resources.</div><div style="font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;"><br /></div><div style="font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;">This map includes short descriptions of geologic units and a cross section showing the distribution of geologic units under the earth’s surface. Among other uses, the map will provide users with a better understanding of the distribution, depths and thickness of Marcellus Shale. This map will be especially useful in showing the interplay between geologic formations and groundwater availability and quality.</div><div style="font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;">https://www.mgs.md.gov/publications/map_pages/garrett_allegany_washington_geo_map.html</div>
