With the holiday weekend, there were lots of visitors in Joshua Tree National Park. Two of those visitors needed rescuing Saturday after they fell in separate incidents. About 11:30 a.m., Morongo Basin Ambulance was called to the Boy Scout Trail area to transport one patient to Hi-Desert Medical Center where the victim was then transported by air to a trauma center. Then, about two hours later, at 1:45 p.m., MBA was called to Hidden Valley campground for another fall victim, who was taken to a trauma center.
