Geology of Colorado (Boulder Valley) - Field Trip #1, Stop #4: Lykins Formation

Prev | Index For This Date | Next

A very interesting modern phenomenon!  The line of bushes across the center of the picture is actually near the contact of the Lyons and Lykins formations.  The bushes thrive here for a reason.  They like to grow in the nutrient rich Lykins formation, but their roots descend into the Lyons sandstone to get more water.  Studies following the contact point have actually been performed just by following these lines of bushes.
