About 150 visitors to Timpanogos Cave National Monument found themselves suddenly stranded Saturday afternoon by Utah's heavy rains.

The park said rangers had to assist about 150 visitors down the trail to the visitor center where they took shelter until the Utah Department of Transportation could clear enough debris to open a lane to canyon traffic. The visitors were allowed to leave about 11 p.m.

On Sunday, both the park and State Road 92 remained closed to visitors while rangers cleared large amounts of rock and debris from the cave trail. However, SR92 opened about 7:15 p.m.

The park service said it hoped to have the trail reopened for hiking by about 8 a.m. Monday, though it warned that additional rain could cause more slides.

Anyone planning to visit Timpanogos cave on Monday is being asked to call 801-756-5238 before arriving for updated information about closures.
