Groundwater Staining in Pennsylvanian Sandstone, West Virginia

Fractures in bedrock transmit groundwater, and geologic mapping is conducted to provide the geologic framework for groundwater resource studies. This photo shows iron-oxide staining (Leisegang banding) from past groundwater flow along fractures formed prior to the rock having been blasted open during road construction. 

This photo was taken along US Hwy 48 near

Mangroves form a protective berm on a Florida Bay island

The transition between a mud flat on the interior of Bob Allen Key (Florida Bay, Everglades National Park) and the mangroves that form the islands’ protective outer berm.  These black mangroves have pneumatophores – parts of the root that function like snorkels, allowing the roots to “breathe” when water overlies the mud flat.

Outcrop-Scale Brittle Fault, Lake Anna

An outcrop-scale brittle fault exposed on the shore of Lake Anna in the vicinity of the Dominion North Anna Power Plant.  The fault offsets a pegmatite dike within biotite granitic gneiss by about 1 meter, in a reserve (top-to-east) sense-of-motion.  The small fault is oriented 235°, with a dip of 30° to the northwest (view is to south in this photograph).
