Ancient Sea Bottom

Yesterday as I was riding to the south of Franktown, CO I spied the below pictured landscape through the haze that dominated the distant mountains.

It reminded me of something I'd seen on either the History channel or the Discovery channel. How Colorado and the surrounding area, back in ancient times, was submerged under a huge inland sea which spanned about a third of what is now the USA.

The haze lent itself to helping you picture the far off landscape as it was as seabottom, with the visible flat-topped hills as old seamounts. Their flat-tops evidence of where the surface of the ancient sea had worn them down to the same level.

Hopefully, you can see the imagery I could see in the panoramic shot above. Picture the ancient sea's surface level with the top of the flat-topped hills and you'll get the idea.

Dear Charlie6 (Dom);

Some day, I am going to get to ride through Colorado. I want to take the steam train to Silverton. I passed through part of Colorado once, but time was of the essence and I had to hustle. I was in Steamboat Springs and went up into the mountains for a conference.

I woke up in the middle of the night, thinking I was having a coronary. I made it to the lobby, where two other people were experiencing similar symptoms. No one told me about this oxygen thing in the Rockies.

Fondest regards,
Jack Riepe

Nice landscape to ride in and the panorama does a fine job showing it. I've been tinkering with them lately to show some of the places I go.

Even though the part of central Pennsylvania I live in is referred to as the ridge and valley region I understand it was an ocean at one time before the ground was uplifted. Explains why sea shells show up in the fossils I guess.
