C and H Refinery Historic District

The C and H Refinery Historic District is a complete industrial complex from the 1930s with original buildings, storage tanks, and working structures still standing. The entire facility demonstrates how crude oil was processed using equipment and methods from that era.

The facility was established in 1933 after its founders obtained and reassembled equipment from a defunct refinery in Casper. It processed crude oil from nearby oil fields and remained an important part of regional industry for decades.

The refinery shows how industry shaped Wyoming in the early 20th century, when small operations became central to local economies. Visitors can see the buildings and equipment that once brought jobs and income to this remote area.

The site preserves its original layout and equipment in a way that can be explored on foot to understand how operations worked. Visitors should wear sturdy shoes since the grounds are industrial and uneven in places.

The refinery gained recognition in the 1990s as the world's smallest functioning oil processing facility of its kind. Despite its tiny size, it demonstrates all the major steps of refining oil in miniature form.
