Interpreting Geological History - Veach Gap

The fourth stop on our soon to be cut short trip ended on a Silurian aged sandstone known as Veach Gap. Located on Massanutten Mountain, Veach Gap is part of the George Washington National Forest.This was one of the most interesting stops by far due to its amazing set of six well formed anticlines (and synclines). Please note the location of Veach Gap below as well as the lower relief towards the center indicating a syncline.

The predominant rock type was quartzite and although the climb was steep and jagged the resulting data and experience were worth the bruises and possible poison ivy. The anticlines were the result of the Alleghanian orogeny around 300 million years ago when Pangaea was coming together. When Africa and Ancestral North America converged on one another the surrounding rock was metamorphosed and folded giving use what we have today, a synclinorium. A synclinorium is a vast elongated syncline with its strata further folded into anticlines and synclines. This can be seen on topographic maps of the area especially when viewing the area around Massanutten.
