Mackay Peak

Elevation: 10,273 ft
Prominence: 480

Climbing and access information for this peak is on Page 262 of the book.


Mackay Peak is the impressive mountain serving as a backdrop to Mackay, Idaho. It is an easy peak to reach, thanks to the mining roads that lead high up its slopes. Miners or Native Americans probably made the first ascent of the peak. USGS Mackay Reservoir

Livingston Douglas made the first recorded ascent of the the peak’s Class 3 Northeast Ridge. As with many Idaho peaks, there is some question as to the exact high point. Livingston discusses this issue in his route description, which is found below.

He has also provided additional details about this peak, which will help you navigate on this mountain:

“Mackay Peak sits above the many old mines that comprise “Mackay’s Mine Hill.” This area has extensive jeep and ATV roads with which to explore the well-preserved relics of an earlier time. Access is via FSR-207 [(A)(3) on Page 264] . When I asked the kind folks at the Mackay Forest Service Office about the condition of Rio Grande Canyon Road, they looked completely perplexed and had no clue what I was talking about. They had never heard of Rio Grande Canyon Road. So I popped out the Mackay and Mackay Reservoir quadrangles and told them that I wanted to climb Mackay Peak. They said something about the “Mine Tour Road” and told me how to get there. Well, hopefully the “Mine Tour Road” will get me to FSR-207. Here are revised, accurate driving directions to climb Mackay Peak.”

The summit area of Mackay Peak is a bit confusing. The discussion of Mackay Peak (Page 262) states that the summit is the Southeast Summit and happens to also be the USGS Mackay Benchmark, as per the Mackay Reservoir quadrangle. But, as the map shows, the Mackay Benchmark (10,273 feet) is NOT the true summit. The map clearly shows that Mackay Peak is about 0.5 mile WNW of Mackay Benchmark and, based on contour lines, is higher than Mackay Benchmark. The true summit of Mackay Peak is at an elevation of 10,280+ feet. I climbed both Mackay Benchmark and Mackay Peak. I can verify by both visual and altimeter readings that Mackay Benchmark is NOT the high point of this peak. As per the map, the Northwest Summit is the high point. Based on my altimeter readings, the Northwest Summit is 20 feet higher than the Southeast Summit, Mackay Benchmark.“

Northeast Ridge, Class 3 by Livingston Douglas

Date of Climb: July 14, 2016

Access

From the junction of US-93 and Main Street in Mackay, drive southwest on Main Street. Main Street turns south and becomes Smelter Avenue. At the 0.9 mile point, cross the bridge over the Big Lost River. At 1.8 miles, notice a large sign for “Mackay’s Mine Hill.” This is where the infamous “Mine Tour” begins. The road is now labeled “MK-207.” At 3.5 miles, the road enters the Challis National Forest and becomes FSR-207. At 3.8 miles, there is a road junction. Go straight on FSR-207 if you wish to climb the North Ridge of Mackay Peak. Park somewhere among the upper mines alongside the road. If you wish to climb the Northeast Ridge of Mackay Peak, turn left here onto FSR-207A and drive 0.1 mile to a road junction. Park here (7,300 feet). Thankfully, the road is a good gravel road to the 3.8-mile road junction.

The Climb

From the parking area, walk back to the main road (FSR-207) and hike west up the road to a three-way junction at 7,680 feet. You are now at the base of the Northeast Ridge of Mackay Peak. Climb west up the steep, open slope. As you approach the forest, turn left/southwest and climb through the open forest without too much difficulty. As you move higher, the terrain gets somewhat steeper and the forest thicker. You will find yourself in a mix of thick pine bushes, krummholz, and blowdown. At a few points, you’ll break out into the open, only to be hit with a short section of steep, large boulders. This is NOT a fun bushwhack.

The ridge itself is rather poorly defined, and you’ll feel more like you’re doing a face climb much of the time. But after 1.5 hours of challenging bushwhacking and boulder hopping/climbing, you’ll reach the base of the summit rocks of Mackay Benchmark. Scramble up the Class 3 boulders to reach the very small summit. Here, find two USGS benchmarks in the boulders, as well as a smattering of triangulation posts, wires, and even a triangulation tripod in reasonably good condition.

If you studied the Mackay Reservoir quadrangle before this climb, then you know the true summit of Mackay Peak is not Mackay Benchmark, but is a rocky outcrop to the WNW of the benchmark. What you may not realize is that the map hides a lot of sins that are embedded in this summit area. It won’t be easy to traverse over to the true summit.

Before I began my traverse to the real summit of Mackay Peak, I returned the wooden triangulation tripod to its old glory. I stood it upright, securing its rickety legs with talus, and positioning it directly atop one of the USGS benchmarks. Now it stands tall and proud, honoring the intrepid surveyors who mapped the western mountains and established all of the elevations of peaks and points that we take for granted. And the summit of Mackay Benchmark is now consistent with all of the wonderfully-maintained mining remains one can visit along the Mackay “Mine Tour” Road. The triangulation tripod is probably visible for miles now, rather than being unseen and rotting on the ground.

Mackay Benchmark-to-Mackay Peak Traverse, Class 2

Okay, so much for sentimentality. Let’s do the traverse to the true summit of Mackay Peak. Move generally in a WNW direction through an open forest that has undulations, large boulders, and short-growth pines thrown in to tangle up your legs. Here are the ups and downs along the way: 80 feet down, 70 feet up, 80 feet down, and 110 feet up. Early on, there is a massive, house-sized boulder that appears to possibly be higher than Mackay Benchmark. So, I scrambled up this monster, just to make sure it wasn’t. And it wasn’t (it was 10 feet lower than Mackay Benchmark), so don’t waste your time climbing it. This will save you a little bit of work, but not much.

After weaving around, bashing through short-growth pines accompanied by some ups and downs, you’ll finally reach the more-open area of the true summit. The actual summit is a boulder (surprise, surprise). No signs of human activity here (not even a cairn). But, thankfully, it looks and measures (by altimeter) to be a measly 10 feet higher than Mackay Benchmark. The USGS map confirms that by rewarding the WNW summit with a higher contour line than Mackay Benchmark (though the benchmark is measured at 10,273 feet, just shy of the next contour line at 10,280 feet). The altimeter and the map concur.

Visually, it’s hard to decipher a 10-foot difference from over 1/4 mile away. The traverse from Mackay Benchmark to Mackay Peak took over 20 minutes of tedious scrambling. I doubt that this summit sees many visitors. I suspect that they are riding their ATVs on the “Mine Tour Road” and are only occasionally staring up at the relatively-indistinguishable, forested peak!
