​​​Clay County 1890 Jail Museum 


Signature Rock


This rock formation is located on what was formerly Lone Star Herford North, just off of Doss Loop, and east of Henrietta on US82.

Cowboys and settlers have for many years carved their initials and dates into the rock. The one in the picture reads MC 1897, and is the oldest we could find. Other dates went from 1897 to 1985. There are literally dozens of initials and dates but many have weathered so much as to be unreadable.
