A pain in the butt
Sitgreaves elevation is 9,388 feet.
It was created by different smaller lava domes forming in the same area and on top of each other, which explains why there are so many false peaks all over the mountain. It sits on the same fault line that Kendrick Peak and Bill Williams Mountain resides. This Mountain stands alone north of I-40 between Flagstaff and Williams. There is no trail to the top. There are many false peaks all over the mountain. To hike the mountain you need the 7.5-minute topo maps of Parks and Sitgreaves Mtn. You need to be good at route finding also. This Peak can be done alone or done with Peak 9,004. Doing it from that route you hike Peak 9,004 along with 3 other false peaks. The climb is very steep up and down on every false peak. The forest is thick enough that you have to rely on the map quite a bit, it's easy to get off course. The hike to the top could take 5 hours, and one hour back down. It takes quite a bit of route finding to get yourself back to your vehicle as well. This mountain is rarely hiked. It sees few visitors.
Where you start is arbitrary. FR833 as mentioned in the description below is not on current maps. It is an old jeep road to the 8368 saddle on the ESE side of Sitgreaves. The Official Route starts from FR66 but there is nothing official about it. Access from Spring Valley Road northwest of the mountain is a popular starting point too.
Start the hike from the bend on FR 833 up a small ridge with a narrow road heading towards the mountain. Once at the end of the road head up a steep ridge on Peak 9004. Near the top it flattens out and becomes an easy walk to the summit. From here you cannot see Sitgreaves Mountain. You have to rely strictly on your topo map and compass to get you across the ridge to Sitgreaves Mountain. It is easy to get off course. From the first false peak to the Peak of Sitgreaves route finding becomes much easier. The constant ascents and descents gets very tiring. From Sitgreaves Peak you can see the general location where you started from. To get down hike to the pass between the Peak and the false peak. Work your way down a ridge to a lower false peak on the side of the mountain. From there head toward a gully on your left and stay in the gully. This gully should take you back to your vehicle. Hiking up this route would be very steep and not very desirable.
