Search and rescue personnel continued searching Yellowstone National Park on Wednesday for a Utah man whose half-brother was found dead on the shores of a lake in the park on Monday.

Officials are searching for Kim Crumbo, 74, by foot, helicopter and boat at Shoshone Lake in the park and will continue to do so for the next several days as long as the weather conditions allow for it.

Park crews on Monday found the body of Mark O’Neill, 67, of Chimacum, Washington, on the east shore of the lake.

O’Neill and Crumbo, of Ogden, Utah, were reported overdue from a four-night backcountry trip to Shoshone Lake by a family member on Sunday.

On Sunday, park crews located a vacant campsite and gear on the south side of the lake, as well as a canoe, paddle, personal floatation devices and other personal belongings on the east shore of the lake.

A Grand Teton National Park interagency ship and crew are also assisting with air operations.

Both O’Neill and Crumbo are National Park Service retirees, and Crumbo is a former Navy Seal.

The incident remains under investigation.

Shoshone Lake, the park’s second-largest, is located at the head of the Lewis River southwest of West Thumb. At 8,050 acres, its average year-round temperature is about 48 degrees. Survival time in the cold water is estimated to be only 20 to 30 minutes.
