OverviewMount Grosh 6351’ and Rose Peak 6291’ are two named summits in the Flowery Range, an offshoot of the Virginia Range of Northwest Nevada. They sit along what is referred to as the Flowery Ridge, east of Virginia City, which rises up to the north above Dayton, NV and US Highway 50. The "Flowery Ridge" should not be confused with the much longer (and larger) ridge where the higher summits of the Flower Range are located. Mount Grosh and Rose Peak are actually on the south side of Six Mile Canyon Road, and follow a parallel ridge heading east.
These summits are both easily accessed from the cities of Reno and Carson City. They are located on mostly public lands, so there are no access issues. Dirt roads lead up to the base of both summits, which are separated by less than ½ mile. They also share a saddle at about 6070’, which is why Rose Peak isn’t an official summit, although Mount Grosh is an official summit.
Both peaks can be hiked in a few hours, and make a great combination with Emma Peak 6442’ just to the northeast. Several other nearby summits can be hiked around these mountains, such as Flowery Peak, and the spectacular Sugarloaf rock formation to the south.
The best time to hike up Mount Grosh and Rose Peak is probably late fall (November, December) and late winter/early spring (February, March, April). During summer, temperatures are far too high. Also try and avoid this area in muddy conditions, after rain storms or snow storms. Wait at least three or four days of dry weather. Not uncommon in the desert, even in winter or springtime.
Getting ThereFrom Reno take 395 to exit 57B, or take exit 61 (Virginia Street) and drive south. Either way leads to Highway 341, the Geiger Grade. The Geiger Grade is a mountain pass road from Reno to Virginia City. It winds through the hills of the Virginia Range for about 15 miles after leaving Virginia Street in south Reno. Once in Virginia City, look for signs to Six Mile Canyon Road. This is a narrow paved road that leads from Highway 341 to US Highway 50 in the Dayton Valley.
The parking area is a dirt road, on the north side of the road (left side of the road if coming from Virginia City). Find a place to park on the dirt road, just past the pavement.
Route DescriptionOnce at the parking area, get back on the paved road and take a left, following it for just under ½ mile until you reach a dirt road on the right, with a metal gate. Walk around the metal gate and follow the road for about ¼ mile until it makes a 180 degree turn. You will see another road on the left just below it. This is the road to take up the into the mountains. Once on this road, follow it for about ¾ miles and there is another road cutting uphill on the right. Take this road as it heads west. It will eventually turn around and head back uphill, and cuts towards a ridge between Rose Peak on the left and Mount Grosh on the right. It ends at a t-junction with another dirt road. Take a right on this road and follow it to the base of Mount Grosh. Try to approach from the right side, as opposed to the left, because the right side gets more sun, and should have less snow in winter and less mud in spring. It is about 370’ up the slope to reach Mount Grosh. Once atop Mount Grosh head down to the saddle between it and Rose Peak, which is about 6070’. Walk straight up Rose Peak, which should take about 10 minutes or so.
To descend, go back to the saddle, and back the way you came. This is about a 6 mile round trip hike, with a total elevation gain of about 1350’. You can add on Emma Peak by descending to the saddle and back to the road. You would descend the face of Emma Peak on the return. Emma Peak adds only another ½ miles net because the descent is quicker once on top of Emma Peak. Emma Peak adds another 620’ of elevation gain.
