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 > Date: Thu, 10 Sep 2009 10:11:47 -0700 > Subject: [ENTS] Re: Record Colorado Redwood! > From: [email protected] > To: [email protected] > > > Florissant definitely looks like a neat place.

The most common kind of "petrified stump" found at Florissant Fossil Beds is the redwood Sequoia, such as "Big Stump" pictured at left. When you visit the park, look for two saw blades embedded into Big Stump; before Florissant was a National Monument, someone tried to cut Big Stump into pieces by using saws! Needless to say, the effort was for the most part, fruitless, and the saw blades are still stuck in Big Stump to this day! > > > > This is a fossil set called the Trio. This "family circle" of fossilized stumps grew out of the single trunk of an older parent tree. The tree trunks are ancient clones, or genetically identical copes, of that parent tree. Modern coastal redwoods also reproduce by stump sprouting. If a redwood is toppled or burned, a ring of new trees often sprouts from burls (roots that stick out of the ground) around the trunk's base. In the coastal redwood forests, family groups are common. But this trio of stone stumps is unique in the world's fossil record!http://www.nps.gov/archive/flfo/online_museum/rocks-fossils/paleontol... > > > > Ed Frank > > > > "Great spirits have always found violent opposition from mediocrities.
