Strobach Mountain and Divide Ridge dominate this high-altitude landscape in Yakima County, where a complex network of creeks drains the eastern slopes of the Cascades. The map reveals a wilderness shaped by water and high meadows, with North Fork Foundation Creek and South Fork Foundation Creek converging near the prominent Foundation Ridge. Recreational and seasonal use is evident through features like the Ahtanum Meadow Campground and the presence of Lost Lake Rd. The terrain is characterized by numerous alpine openings such as Sleepy Park Meadow, Golden Meadow, and the interestingly named Dead Horse Flats. To the north, Fish Lake and Long Lake sit near the headwaters of Fish Creek and Milk Creek, while landmarks like Dome Peak and Ewe Neck provide significant navigational points for those traversing this remote region.
