This valley is from a mile to a mile and a quarter in width. About 
two miles northeast of the hot springs, where West Branch of Gulpha 
Creek cuts through North Mountain, is a limited area with an elevation 
of about 620 feet. The greater part of the surface, however, stands above 
the 700-foot contour, and the highest hills exceed SOO feet. The highest 
elevation at which any of the springs emerge is about 640 feet.
