Leah Hogsten | The Salt Lake Tribune Sandy Borthwick, biologist at Capitol Reef National Park, hunts for two endangered cactus: Winkler cactus and Wright fish hook cactus. All of the world's Winkler cactus growing in the wild are found in Wayne County and a sliver of Sevier County.

If you haven't read reporter Brandon Loomis' report on the unique challenge facing rangers at Capitol Reef National Park — preventing the theft of rare cacti — do yourself a favor and get educated.
