Basalt is a common volcanic rock commonly called lava. During the
cooling of a thick lava flow, contractional joints or fractures
form. If a flow cools relatively rapidly, significant contraction
forces build up. While a flow can shrink in the vertical dimension
without fracturing, it cannot easily accommodate shrinking in the
horizontal direction unless cracks form; the extensive fracture
network that develops results in the formation of columns. The
topology of the lateral shapes of these columns can broadly be
classed as a random cellular network. These structures are often
erroneously described as being predominantly hexagonal. In reality,
the mean number of sides of all the columns in such a structure is
indeed six (by geometrical definition), but polygons with three to
twelve or more sides can be observed. Here you will find a small
version of the Devils' Postpile National Monument in CA or the
Devil's Tower National Monument in WY.
The cache is a cylindrical cookie tin hidden in the crevices
between the posts. The location is accessible year round with a
high clearance vehicle but some times during the years 4WD may be
necessary. You can drive within a hundred feet but you will have to
climb over rocks on foot to reach it.
The cache was place in April during the Nevada Trophy Rally but I
delayed releasing it due to a nesting raptor on the top of the
postpile.
