Geology of a Geomorph

Geomorphic Threshold = The amount of SLOW accumulated change a landform can take before it suddenly moves into an ACCELERATED rate of change that takes it to a new system state. In other words, this lonely (granite) landform has very well-developed planar fractures, (maybe I should ask it out to dinner), and it will soon tumble to the ground. Luckily, I got this picture before that happened. And if it would have fell on me, it most definately would have spoiled my weekend. Taken in The Boulders area southwest of Payson, Arizona ~ February 5, 2008 ~ Radon Study : Some granitic rocks have anomalously high levels of URANIUM. Homes built on granite rocks and decomposed granite seem to have the greatest potential for elevated radon levels, even if underlying rocks contain average amounts. This may be because fractured and weathered granitic rocks have greater permeability than other rock types, and a larger proportion of the radon present in the rock can escape.
