Start up the old mining road and skirt around the yellow gate. Follow the road as it climbs parallel to the highway. At the first fork in the road, where going straight would descend, take a left uphill. You will soon come to some mining relics and a small clearning. Walk straight to the very end of the clearing where a less established trail contours upwards.
Follow the trail, which may have pipes and tubings running towards the gulley. The trail stops at the gulley. Make your way upwards from here along the goat trail along the ridge. You will follow this ridge for quite a ways up.
Shortly you will come to a small rock face on the ridge which you can either climb straight up or skirt around the right side. You will pass through some stunted trees which should have goat paths leading through them. Higher up, look for a somewhat worn goat trail that will cut across your trail. Follow this goat trail to the left (south) as it heads towards Dail Peak. At any time now, pick your way up the open hillside to the top of the ridge. At the top of the ridge, you will overlook a high plateau which is connected to Montana Mountain
Make your way to the left (south) up the rocky section which will feel like a small false summit. From here, continue along the ridge to the base of Dail Peak. The ridge is broad and has some knarly rock formations on the east side (your left). It is a short walk up to the summit from here.
Follow the same trail back. Do not be tempted to descend one of the other gulleys, even though they may look safe and more direct. About three quarters of the way down these gulleys, there are sheer cliffs and waterfalls, which will force you to hike frustratingly back up the way you just came down. It may look promising from the top of the ridge, but will actually take you longer and require a lot of bushwacking if you attempt it.
