This is what you see a lot of when you take the Northshore Road inside the spectacular Lake Mead Nat'l Rec. Area.
GEOLOGY in a NUTSHELL:
The white rock (Callville limestone), is much older than the dark "top" of Black Mesa, which is a basaltic pluton that came to the surface and cooled.
CALLVILLE area history:
The Mormon Church, on their expansion west, needed a reliable route
for their supplies to reach Salt Lake City, Utah. Elder Anson Call was
sent to select a site for a steamboat port and, in 1864, he established
Callville. The Mormon's PLAN for a supply route via the COLORADO RIVER
was abandoned when the transcontinental railroad was completed in Nevada
in 1869. STEAMBOATS and barges trading SALT between Rioville and El
Dorado still made a few stops at Callville. NPS and concession developments at Callville Bay (on Lake Mead) began in 1967, after the
Northshore Road was completed around 1966.
Black Mesa lies due south of the Callville Bay road, and can be climbed
with knowledge of scrambling and topo maps. Its summit is 2,201 feet above
sea level, and goes without saying that it gets very warm here in SUMMER.
Please bring plenty of water. (Photo taken in early March of 2008)
