Note: Dalton NW7 refers to the unnamed peak which is 7 kms northwest of Dalton Peak.
The first three quarters of the trail is the same as the King's Throne
hike, starting off along the old mining road that follows through the forest and along Kathleen Lake. You will reach a fork in the road and a sign showing King's Throne to the left and Cottonwood Trail to the right. Take the left trail which leads steadily uphill, eventually turning into switchbacks that take you up and out of the trees and onto the steep, loose rocks of the rock glacier. There is a well-marked trail all the way to the seat of the King's Throne (an elevation gain of 500 m). From the seat of the throne, a trail leads steeply up the left (southeast) ridge, if you're facing the mountain.
The hike up the ridge is steep and winding for another 690 m elevation gain over approximately 2.3 km, but eventually mellows out as you approach the saddle between King's Throne and Dalton NW7. From the King's Throne trail, you will need to drop down to your left slightly to gain the ridge to Dalton NW7 (directly south). There is a gentle approach to the base of the rocky ridge that leads to the summit; this approach is often flanked with snow on the east side which remains all year round.
The route climbs up steeply to a smaller sub peak and then slightly down and along a narrow ridge until the final climb up to the true summit (2,112 m). There are some technical sections where you will have to use your hands and ensure proper footing (ropes are not necessary). There is also a lot of loose rock, so give your hiking partner(s) lots of space. The views from the top are amazing as you enjoy the same view as the summit of King's Throne looking down Kathleen Lake with the added benefit of being closer to the other peaks of the Dalton Range.
