Park rangers urge visitors to be prepared for high summer temperatures 
Search and rescue team responded to four heat-related callouts in June 
TWENTYNINE PALMS, Calif.– Rangers at Joshua Tree National Park are urging visitors to take extra safety precautions when visiting the park during the summer season due to high temperatures, extreme ultraviolet rays, and harsh exposure.
Visitors should plan ahead, be prepared and bring extra food and water, consider going on shorter hikes and use extreme caution. Hiking in the middle of the day, between 10 a.m. and 5 p.m. when it’s the hottest, is not recommended.  
“We ask that park visitors consider taking advantage of shorter trails closer to sunrise and sunset, stargazing under the dark night sky, and visiting the park’s visitor centers and exhibits,” said Anna Marini, coordinator for the Joshua Tree Preventative Search and Rescue (PSAR), a volunteer team that specializes in visitor education. “Please keep rescuers and yourself safe.” 
PSAR members, spoke to nearly 2,500 visitors at trailheads and on the trails in June. Three hundred contacts identified significant safety concerns, and reduced risks to visitors by suggesting different shorter trails, being better prepared with food and water, and providing safety tips.
Joshua Tree’s Search and Rescue Team (JOSAR), an all-volunteer team, responded to four incidents involving heat illness in June between the peak heat hours of 10 a.m. to 5 p.m. Two of these were on trails longer than two miles, including 49 Palms and North View Trail. 
Temperatures in the triple digits have already been recorded in lower elevations. The park can see temperatures as high as 120 degrees Fahrenheit. There is no water or shade inside the park. Hiking in extreme heat can lead to serious health risks, including heat stroke, hyponatremia, and death. Signs of heat stroke can range from nausea, vomiting, headache and/or cramps, weak and rapid pulse, high body temperature, confusion, unconsciousness and/or seizures. The health effects of heat exposure can happen to anyone.
