The trail is tough. It is 2.8 miles one way and starts at an elevation of 785′ and finishes up at 4150′. I had my Nikon FM3a with the Nikkor 50mm F2 lens attached. I used Kodak 400tx and pushed it one stop. The trail has very bright areas where everything is reaching to the light and very dark and somber areas, where the absence of any sounds creates a surreal effect. I developed the film in HC-110(B) for 4 minutes, 45 seconds, @20C.
