Reply to comment by DistortoiseLP in TIL redwood trees -- growing to heights of 350 feet or more (over 100 meters) -- have roots that go only about ten feet into the ground. by OccludedFug
Not in cali, tho. IN the national park west of Pike's peak, called Florissant Fossil Beds, there are fossil remains of Sequoia leaves there and those were as old as dinos.
The Rocky Mtn. Orogeny was volcanic and likely due to subduction over the pacific plate there. Hard to realize that most of western US was not there 75 M yrs. ago. The Rockies may have been as high as 16-20K feet high peaks back then too.
There are some good geological guides to the Central Rockies.
