Short description: Wildflowers at Point of Rocks north of Elkhart in Morton County. Point of Rocks was a much-anticipated landmark for wagon trains on the Santa Fe Trail. The white beds of Neogene Ogallala Formation calcrete overlie older Permian-age beds of shale, siltstone, and sandstone. Point of Rocks was listed on the National Register of Historic Places in 2013 as part of a thematic Historic Resources of the Santa Fe Trail nomination.
