We stopped by here for lunch last week on our way back from Colorado. It's an historic LDS site at the intersection of I-70 and I-15 in central Utah. There's a beautiful picnic grove and guided tours of the fort.
Cove Fort was built in 1867 to protect the telegraph lines between Logan and St. George from Indian attacks. The attacks never came. Nevertheless, the fort served as an important outpost for local Mormon settlers as well as a way station for travelers through the territory. Its telegraph and mail services were important communications links until the early 20th century when the fort was no longer needed. It fell into disrepair but beginning in 1988 was restored to its original appearance and furnished with original artifacts as well as historic items from the period.
Given the remote Utah location and severe climate, the fort provided surprisingly nice accommodations for the Hinckley family who built it and lived there, and for the travelers passing through.
