The Rapid City man who died Saturday in a mountain biking accident near Rockerville has been identified as Curtis James VanOsdel, 21.
VanOsdel was riding down a steep hill on a U.S. Forest Service Trail commonly referred to a the Phoenix. He hit a rock, lost control of his bike, came off the bike and hit a tree, according to Pennington County Sheriff's Sgt. Greg Foster.
VanOsdel suffered a serious head injury. He was pronounced dead upon arrival at Rapid City Regional Hospital.
He was wearing a helmet and was said to be an experienced rider. "It was just a tragic accident," Foster said.
A notice was posted about the accident to other mountain bikers by the Black Hills Mountain Bike Association on its website Sunday. The association asked riders to stay off the trails on Storm Mountain, where the accident occurred.
"With the tragic events of Saturday, April 6, we are asking that riders please refrain from using the trails at Storm Mtn until further notice," the website said. "Our thoughts are with the rider's family."
President of BHMBA Roger St. Pierre said the group was asking riders to stay off the trails to give law enforcement a 24 hour window to do any forensic investigating.
