The geology is in turn inextricably entwined with Colorado's human history.

Given enough time, cold surface rock will yield to flowing water and buried rock will bend or even flow rather than break.

The planet's had ample time for all of this, even if it's out of our ken.

My piano tuner's job security rests on the fact that properly tuned piano wire flows (stretches) at a similar rate and falls out of tune in a matter of months.

Over a few Ma, fingernail speed is plenty fast enough to fold great thicknesses of sedimentary rock over the east edge of the relatively brittle Front Range basement block, as in the photo at right.

I've attempted to point out the most significant unknowns and disagreements, but often, rightly or wrongly, I've simply taken sides.

If you take nothing else away from this humble attempt, please consider this: Of Colorado's 55 Fourteeners, all but 2 (Longs Peak and Pikes Peak) lie either along the Colorado Mineral Belt or on the shoulders of the Rio Grande Rift.

Under great confining pressures, or at depths where temperatures reach a significant fraction of their melting points (typically 10-15 km), rocks that are quite brittle at the surface become sufficiently plastic to deform without fracture at rates comparable to the rate at which fingernails grow (~10 mm/yr).

Granted, that makes molasses look downright mercurial, but then relative viscosity is the whole idea here.

With over 50 million modern human lifetimes elapsed since the planet formed around 4.5 Ga, geologic or deep time is, to say the least, difficult to grasp.

But the effort pays, for with a feel for deep time comes a sense of its great power: Given enough time, almost anything energetically possible can happeneven at very large scales.

Colorado's also part of an immense, heterogeneous and longstanding tectonic upland covering the entire western third of the United States and ultimately can only be understood in that context.
