Medical emergency turns fatal on Moab’s Poison Spider Trail
A rider on Poison Spider Trail suffered a medical emergency on March 28 and died on scene, even after SAR, EMS and a helicopter rushed in.
A call for help on Poison Spider Trail turned into a full-scale rescue response, but the rider at the center of it died on scene anyway. Grand County Search and Rescue was dispatched March 28 after a person riding an off-highway vehicle on the Moab trail suffered a medical emergency, bringing in SAR, EMS and a medical helicopter in a race against distance and time.
The incident hit one of Moab’s most recognizable four-wheel-drive routes, where steep sandstone climbs, ledges and wide-open desert views usually define the day. The Bureau of Land Management says the Poison Spider Mesa Trailhead opens access to the 16-mile Poison Spider Mesa 4x4 and mountain bike loop, the Golden Spike Route and nearby hiking trails. Discover Moab describes the Poison Spider 4x4 as an 8.4-mile rough road rated intermediate-plus to advanced, with a physically demanding descent of more than 1,000 feet from the Portal Trail start to SR-279.
That terrain is part of what draws experienced drivers and passengers, but this case underscored how fast a non-crash emergency can become fatal far from town. The rider’s death was not framed as a trail flaw or vehicle failure. Instead, it highlighted the reality that medical trouble can surface in the middle of a recreation run, when the nearest pavement, signal and hospital are all still a long way off.
The timing matters too. The emergency unfolded during one of Moab’s busiest outdoor stretches, when the region’s trails, canyons and four-wheel-drive routes fill with visitors looking for spring conditions. Grand County’s Trail Ambassador Program includes Poison Spider OHV trails among its high-use coverage and says it was created in 2021 to improve visitor safety, promote Leave No Trace and Tread Lightly practices, and reduce conflict on the ground.
Grand County Search and Rescue describes itself as the busiest search and rescue team in Utah, and the call volume shows why that label sticks. Public reporting said the team handled 20 incidents in October 2025, and another report said Grand County’s search-and-rescue system logged 143 incidents in 2025 across mountain biking trails, canyons, rivers and remote desert terrain. Poison Spider now joins that larger picture as a reminder that on Moab’s backcountry routes, the margin between a good day out and a fatal emergency can be vanishingly small.
