In the Mojave Desert of southeasternmost California is a remarkably
smooth, symmetrical rock-alluvial dome which takes its name
from Cima on the Union Pacific Railroad. Lawson (1915, pp. 26, 33)
cited Cima Dome as a prime example of a panfan, but Thompson
(1929, p. 550) later showed that its upper part is bare rock. Davis
(1933, pp. 240-243) considered it a fine example of a convex desert
dome evolved from back-wearing of a fault block, but this concept
is contradicted by the geological relations (Hewett, 1954), which
throw more light on the nature and origin of Cima Dome than do
geomorphological theories
