Here is an overview of the various photos of the course. http://www.mogollonmonster100.com/1/post/2013/07/the-magic-of-pictures.html
Here is a video the Zane Grey 50 Miler in 2013 made by Andrew Neugebauer. I'm personally responsible for about 298 of their views and recommend you watch this if you haven't already. It portrays the area well, and captures the rugged beauty of the course and Mogollon Rim really well. If you are coming from out of town or country and are thinking the course is a desert, this will give you a more accurate portrayal of what you can expect. Plus, it's simply an incredible video. Enjoy.
Zane Grey Highline 50M
I included the below video I made after the Zane Grey 50 Mile race in April 2012 because the race shares the same starting line, Geronimo Aid Station, Washington Park aid station and Hell's Gate Aid Station. Same locations, and for those small portions of the course that experience will be similar. Having said that, it's only 14 miles of 106 that are the same but the video at least lends to an idea of what the terrain and locations of aid stations will look like.
MOG100 Trial Run
Very brief video of the Highline Trial #31 at sundown after leaving Washington Park aid station for the second time. You leave the aid station and head out on some rough terrain up and down the edge of the Mogollon Rim before reaching the Hell's Gate aid station and then a couple miles later, the Myrtle Trail. This is about 52 miles into the day here when I took the video. It was on the day of the "Super Moon" on May 5th which was absolutely spectacular. Really, it was incredible.
Mogollon Monster 100 Cabin Loop
The Cabin Loop is first experienced after reaching the Washington Park Aid Station around 26 miles into the day. You'll climb the Rim and enter the forest on this network of trails along rivers, through the meadows and along canyons. This video was taken in April a week after the last snow so there was little greenery at the time, which has since drastically changed as spring arrived.
