Overview: This southeast approach to Lucky Peak (AKA Shaw Mountain) begins at the Boise River WMA following a dirt road that travels northwest along creek with burned vegetation from the Mile Marker 14 Fire July 2016. It has less usage and more trees than the Homestead Trail approach from the southwest. It passes an intersection to a road leading to Adelmann Mine, then climbs ridge to the summit. Elk herds and deer often present. Spectacular views of Treasure Valley and Boise National Forest close to Boise. Side trip to Adelmann Mine with historic buildings not far from main road.
Difficulty: moderate with no snow; moderate - strenuous with snow. Route-finding skills needed if going off road and onto ridge.
Elevation gain: Boise River Wilderness Management Area (trailhead) at 3,624': Lucky Peak elevation 5,904' = ~ 2,280 feet.
Lucky Peak Coordinates: 43°36'18.82"N, 116°03'39.98"W. Boise River Wilderness Management Area Coordinates: 43°34'26.7"N, 116°1'18.62"W
Map: USGS Lucky Peak quad, 7.5-min series
Distance: 7 miles out and back.
Directions to trailhead: Boise River WMA is on the west side of ID-21, 6.8 miles from E. Warm Springs Rd. and ID-21 intersection east of Boise. It is a left hand turn to a small parking area with a gate just after Highland Valley Summit if you are heading north.
Geology: Granite of Idaho Batholith, Cretaceous age 117 - 62 million years ago.
History: Adelmann Mine's primary mineral was gold.
A good friend commented, after reading my last post on Cervidae Peak, that Fred and I were "lucky" to have Lucky Peak as a training mountain. We've hiked it many times during the 18 years that we have lived in Boise. When we hike "the front side" of Lucky via Homestead Trail, the elevation gain is 3,000 feet and we always try to improve our time.
This time we snowshoed what we call the "back side" after a late winter snowstorm. Snow depths varied from a few inches at the trailhead to ~ 12 inches at the summit. A steady breeze from the northwest provided a good headwind for most of the climb. The visibility at the summit was 300 yards, and hard rime ice created by heavy fog coated fir branches and last season's blue-bunch wheatgrass. Fred and I took turns breaking trail through untracked snow. On our way down, the clouds broke revealing a spectacular winter scene with views of the Boise National Forest to the northeast, Lucky Peak Lake to the southeast, and the Owyhee Mountain range to the south. The contrast between the flat, dark Treasure Valley under shifting clouds and the bright white snow of mountains stretching to the horizon was of jaw-dropping beauty, the kind that makes you stop in your tracks. Idaho is an incredible place!

Our route to Lucky Peak (AKA Shaw Mountain) from Boise River WMA on ID Highway 21. This route intersects with Route E. Shaw Mountain Road near the summit (on left). Total hiking distance ~ 3.5 miles to summit with 2,280 feet of elevation gain.
This trail begins at the Boise River WMA buildings, following an often-muddy road in a northwest direction, with the tree line of Lucky Peak coming into view in about .5 miles. It crosses a creek, then begins a steep climb for 1 mile to the intersection of the road that leads to the abandoned buildings of Adelmann mine. At this intersection, take the road to the left for a short climb to a ridge overlooking the valley to the south. The road continues to the northwest and can be followed to the summit; it's here that we get off the road and take the more direct ridge route, beginning at two log stumps and a "No Motor Vehicles" sign. We gain the ridge where the snow is wind-blown and not as deep and follow it towards the tree line on the right. Toward the top, there is an intersection with E. Shaw Mountain Road, marked by a wooden birdhouse. Our route continues on this road to an outhouse with the radio towers of Lucky Peak in view, then a short steep climb to the top.
Point at which we leave the road to climb to ridge: this is on a saddle separating Adelmann Mine to the north and Black Hornet Mine to the south

Hard rime ice had accumulated on the windward side of everything enveloped in the fog at the top. We cleared a place in the snow, sat and ate lunch until we cooled down from the climb. As we hiked down, the clouds thinned, illuminating trees, grasses and shrubs in a golden light, and a little further down we found ourselves in bright white fresh snow, walking toward the dark blue and white peaks of the Boise National Forest. Since Lucky Peak is the highest point for miles around, it gives you the feeling that you are walking above almost everything else.

There's lots of advantages to snowshoeing vs. hiking with no snow: vegetation is not damaged, you sharpen navigational and preparation skills, and best of all, quiet and solitude. We went up into the clouds facing a steady headwind and came down in sun and breaking clouds with warmer temperatures. We are lucky in Boise to have the opportunity to experience great snowshoeing treks.
Short and steep hike along ridge overlooking Lucky Peak Reservoir with great views, Boise National Forest
Overview: Trail to Cervidae Peak is only 17 miles east of Boise and traverses along the ridge between Mores Creek to the west and Lucky Peak Reservoir to the south. Vegetation includes bunch grasses, rabbitbrush, antelope bitterbrush and sagebrush. Spectacular views of Spring Shores Marina and Lucky Peak Reservoir to the south, Lucky Peak to the west, and Shafer Butte to the northwest.
Distance: 2.3 miles to summit (according to my GPS)
Elevation Gain: Trailhead at 3,120 feet, summit at 4,987 feet = 1,867 feet. Add to this ~ 120 feet of elevation due to loss/gain on ridge - Total elevation gain ~ 2,000 feet in 2.3 miles.
Coordinates: Cervidae Peak: 43°36'50.66"N, 115°58'26.75"W.
Driving Directions: Drive ID-21 north from Boise past Lucky Peak Dam, over Highland Summit. Cross over the High Bridge that crosses Mores Creek with vertical basalt cliffs. Almost immediately after the bridge, turn right on FS-269 that leads to Spring Shores Marina and Atlanta. About 2 miles past the marina, park on the right in a large pull-out. Trailhead at large gate across road.
Trail: After passing the gate, the trail starts to the left of a short gravel road, where it contours the bottom of the southeast ridge heading east and then turns to the northwest, gaining the ridge. The trail is well-worn and heads straight up the southeast ridge to the summit.

Cervidae Peak is one of the 4 "Grand Slam Peaks" that Tom Lopez, author of Idaho: A Climbing Guide describes. The other 3 peaks are Mt. Heinen, Kepros Mountain, and Lucky Peak, all close to Boise. As Tom Lopez does, Fred and I use Cervidae and Lucky Peak to train for our summer mountain summit hikes. We discovered Cervidae when we wanted to add variety to our usual Lucky Peak training.
Cervidae Peak is great for a lot of reasons: it's close to Boise, the trail is steep with no switchbacks once you get on the ridge, so you can get a decent work-out in a short amount of time and see some awesome views. It's a great opportunity to get a good view of Lucky Peak Reservoir and identify landmarks at the 360 degree view at the top. The family Cervidae is a scientific classification that includes deer, elk, moose and reindeer.

The Lucky Peak Dam was built in 1955 to be included in the system of flood control and use of irrigation water from the Boise River. This was done mainly as an assurance to water users of the Boise River system that their supply of water would be protected and the Arrowrock Dam and Anderson Ranch Dam above the Lucky Peak Dam could be drained down during flood control measures. It was a way of adding water capacity; building Anderson Ranch and Lucky Peak reservoirs were moves toward multiple-use reservoirs.
The Reclamation Service, a U.S. Federal government agency started construction of Arrowrock Dam, a few miles further upstream from Cervidae's trailhead on the Boise River for the purpose of storing water for irrigation in the early 1900's. Arrowrock Dam was dedicated in 1915 by Reclamation; it was the tallest dam in the world at that time and 4,000 people gathered to witness the dedication. The report, History of Boise River Reservoir Operations gives a great history and overview of management of the Boise River.
Large granitic intrusions during Cretaceous time (144 - 65 mya) that formed the Idaho Batholith make up the bedrock of Cervidae and the upper Boise River drainage. Cervidae Peak can also be summited from its west ridge; it's near this access where basalt dikes that cut through the granitic basement are seen along the east side of ID 21 a few miles past the high bridge that spans vertical basalt cliffs.
No switchbacks here - Cervidae is on right side of ridgeline

Most of the trail is steep and it's about all that you can see in front of you at times, but then you get to a rise on the ridge and see expansive views. About 3/4 of the way up this trail, the trail from the west side of the ridge intersects. This trail is accessed from Highway 21 and provides a more direct hike to the summit. The trail loses some elevation near the summit only to regain it, followed by less steep terrain toward the top.
We found a register at the summit pile of granite. A steady, bitter cold breeze had made us cold despite having climbed almost 2,000 feet. Surprisingly, the summit was calm but cold. Looking toward the northeast, we tried to identify Mount Heinen, a climb on our spring bucket list.
We did this hike with 2 friends a couple of summers ago - in the afternoon! Not the best time to do this hike - it was hot and there's no shade. This is a good late winter/early spring hike.
