Apparently No. 27 of this section agrees with No. 6 of the Victoria 
section and both may be regarded as Frio clays. This would give 
these clays a dip of 20 feet per mile in this region. 
This well is drilled about half a mile from the shore of Matagorda 
Bay and 3 miles southeast of the old town of Indianola. 
Within this area four of the small elevated areas occur. These 
are Big Hill, in Matagorda County ; Bryan Heights, near Velasco ; 
Kiser Heights, at Columbia, and Damon Mound, near the northern 
side of Brazoria County. The first two are comparatively low, and 
might probably be overlooked by the traveler. Damon Mound (see 
fig. 1), however, is a very prominent feature. Situated on the north- 
ern side of Brazoria County, on the Darst league, it forms a very 
prominent feature in the landscape. For at least 20 miles in any 
direction the surrounding country is a low, level prairie. The mound 
itself rises somewhat abruptly to an approximate height of 83 feet
