You may not know the name of this mountain but, she knows you...
if you've driven through the Arm more than a couple times, you've definitely seen it.
If you're driving back into Anchorage, it's visible as you're approaching the small village of "Indian" (home to one of the best restaurants in the state: Froth & Forage, https://www.yelp.com/biz/froth-and-forage-coffeehouse-and-eatery-anchorage)
It's flanked by two official trails:
Falls Creek Trail: on the "Anchorage side" (west)

Indian Valley Trail: on the "Indian, AK side" (east)

The trail that goes up to Indianhouse is not an "official trail". Because of this, I was always leery about climbing Indianhouse Mountain. I'm not super-thrilled about bushwhacking, and I thought getting to the mountain proper would require a ton of it.
Oh, how wrong I was!
The trail that goes up here is actually shockingly well maintained. No 'schwacking at all! It is, however, incredibly steep. Probably steepest trail I've been on in the Chugach State Park area (maybe that's why it's not "official").
Anyway, for the first (steep) mile, it's a very steep hike. You'll eventually top out on nice, wide prairie-like area. From here, casual hikers should probably turn around. You'll know you're at the turnaround point because the trail will start to become faint and eventually disappear into a ridge that leads to the much larger ridge of Indianhouse Mountain.
To summit Indianhouse, DO NOT ride this ridge up to ridge of Indianhouse and then try to take that to the summit! This is a tempting move to make but the rock that lies ahead for you is of very poor quality and the moves are very much 5th-class! (e.g. you'll need a rope)
Go partially up the ridge, but, before you connect with the summit ridge traverse right. And keep traversing right. This...can be kinda bushwhacky, but you're largely on tundra (and/or garbage snow). I'd say this is probably the crux of the hike/climb.
You're looking for a large couloir (narrow gully) that leads up to the summit. It usually has snow in it until later in the summer. You might want to bring an ice axe and crampons or, at the very least, a trekking pole and some microspikes.
The summit is exposed and complex, with incredible views in all directions. Views of the nearby Suicide Peaks are one-of-a-kind! read more
