Having visited Monument Rocks last year, we were excited when we had the opportunity to swing by this unusual geological formation on the way to Lindsborg a few weeks ago. These fossil encrusted limestone structures are remnants from the time when Kansas was at the bottom of an ocean, and are 2-3 stories tall. It's interesting how they rise up all of a sudden in otherwise non-descript prairie pasture (read flat) land. Well worth a visit if you're ever close to the area. Note: the black specks in the first picture are the birds that build mud nests near the top of the arch.
