The Oklahoma State Highest Point, Black Mesa


I am told it is a male collared lizard, Crotaphytus collaris

The collared lizard is the state reptile of Oklahoma, where it is known as the Mountain Boomer.


Black Mesa is the highest point in Oklahoma at 4,975 feet above sea-level. Black Mesa is located in Oklahoma's panhandle along the tri-state border with Colorado and New Mexico. It is named from the layer of black lava rock that coated the mesa about 30 million years ago. Igneous rocks are much more durable and erosion-resistant than the sedimentary rocks that they overlay; thus, the borders of the lava flow form a sort of cap that prevents the rock beneath them from being eroded as quickly as the rock immediately next to the flow's boundary. This type of process is what formed Black Mesa. Mesa comes from Spanish and Portuguese meaning "table" or "table mountain".
