Someone had an accident on a trail. Medivac helicopters, firemen, police, and ambulances made this hike a bit more exciting than usual. Add to this it was sunset, and it was rather surprising to turn the corner to see this.
15 / 365 Emergency on the Corner

Hope everyone involved in the crash survived!
Actually, to my understanding, a hiker fainted or something along a trail. The ambulance is on a fire road into the area. There was also a medivac helicopter. Where the helicopter was is a steep canyon, with only a trail to get in and out. Looking in the papers, nothing I can find. It was very curious. And, like you, I hope all are well.
