Gary- I don't know the answers to all your questions, but the presence of redwoods in Colorado had less to do with glaciation than the significant geological uplift that raised what was once a seabed like the states to the east of Colorado, and what became the Rocky Mountains running from New Mexico into Canada. Glaciation followed later. -Don
