Program topic

BBNP has seen a dramatic increase in first-time visitors during the past few years, and the number of heat-related rescues and fatalities have increased as well. Because of this, the park implemented the PSAR program in May 2021 to educate visitors in the prevention and treatment of heat illness.

For the past three summers, Alan and Cheryl have lived in the Chisos Mountains for the months of May, June and July. Together with a team of other PSAR volunteers, they have assisted hundreds of visitors suffering from heat related illnesses and saved countless lives.

On a daily basis, PSAR rangers greet visitors at the Chisos Basin Trailhead to guide them towards experiences that will keep them safe and help them enjoy BBNP to the fullest. This trailhead in the Chisos Basin is the busiest destination in the park because multiple hikes begin at this location.

Hikes from the Basin Trailhead range in duration from fifteen minutes to three days, including overnight backpacking in the mountains and desert. Day hikers are the most likely visitors to experience heat illness.

The PSAR team makes sure that visitors have adequate water, food, electrolytes, experience, and knowledge of the trails they plan to hike. They suggest strategies that will keep them safe in the Chihuahuan desert and Chisos Mountains environments. They also alert visitors about what to do if they encounter wildlife such as bears, mountain lions, javelina and venomous snakes.

Using radios, the PSAR team monitors the trails to determine if anyone needs assistance. Nearly every day, one or more PSAR volunteers hikes portions of the Window Trail to assist hikers. The Window Trail has more rescues than any other trail in the park. The PSAR team also joins the park’s Search and Rescue (SAR) team when additional personnel are needed. 

Join Alan and Cheryl to learn how you and your family and friends can prevent heat illness in an outdoor environment. Learn about the early signs and symptoms of heat illness and how to assist someone who may be experiencing heat exhaustion or heatstroke. The knowledge you gain from this program may save your life or the life of someone you care about!
