Imagine me speaking in a nerdy pseudo-scientific voice)-
Actually, Lone Mountain is an example of a Lacolith intrusion. Picture a bubble of hot magma advancing to the surface of the earths crust but never breaking through. The bubble forms a bulge that is many thousands of feet higher than the surrounding geology. Over millions of years, wind & weather erode the overlying cover and reach the harder lower material of the intrusion. This material resists erosion so it remains while erosion continues to carry away materials around it. Eventually this leaves Lone Mountain.
The rock is type (andesite or dacite) Andesite is an igneous
, volcanic rock
, of intermediate composition
, with aphanitic
texture. The mineral
assembly is typically dominated by plagioclase
are common accessory minerals. Alkali feldspar
may be present in minor amounts) that is usually lots of flat plates lying about. It is unusual to near impossible to find what would be considered a boulder or a cobble. Just millions upon millions of these flat plates. The crystal structure of the plates is very hard and brittle, and sharp really really sharp.
And then there are the elves. They are disguised as Picas but really they are rock sharpening elves. Unhappy to have to share their powder with the skiers, they spend all fall with 12" mill bastard files sharpening the rocks in the most popular lines.
Another crew of elves then tips the sharpened plates up on edge and braces them. then all the elves retreat to their lairs and await the screams of the unwary as they rip their bases and slice their P-tex. The elves then return to feed on the lost P-tex.
