Mount Tonsa is situated in the valley called "The Valley of the Ten Peaks" which explains the name. While most of the others have names this one does not, at least according to Sean Dougherty's "Selected Climbs in the Canadian Rockies".
The others in the area are:
Mount Fay (Peak 1)
Mount Little (Peak 2)
Mount Bowlen (Peak 3)
Mount Tonsa (Peak 4)
Mount Perren (Peak 5)
Mount Allen (Peak 6)
Mount Turzo (Peak 7)
Mount Deltaform (Peak 8)
I am unsure of the other two but I will assume Mount Bable and Mount Quadra fill in the other two spaces on the list.
Peak 4 is one of the scrambles in the area of the ten peaks once you have reached the hut. Its route description is very similar to Mount Bowlen as well. The guide book mentions this as very straightforward with no technical difficulties. Heading across the glacier to the left of the hut and straight up the face. It is approximately 2-3 hours round trip from this point. This can be done in a morning allowing you plenty of time to do another peak or descend to Moraine lake and out. The difficulty here is the approach to the Neil Colgan hut. There are two recommended approaches The Perren Route and the Schiesser Ledges. Bank on 5-6 hours to get to the Hut from Moraine Lake.
Park in the lot and follow the trail right along Moraine lake. You will pass the trail up to the Larch valley for those headed to Mount Temple and or Eiffel Peak. Continue all the way along till you get to the end of the lake. Here you will have to cross the inlet stream twice. There is a cable to hang onto and logs and stones to walk on. They can be slippery so be careful unless you want wet feet. Once you cross these you follow the trail winding through some small trees till you reach the rock and rubble. At this point you bear left more for the Perren Route and more to the right for the Schiesser Ledges.
Trails can be closed due to bear activity but this rarely involved the trail/routes to the Neil Colgan hut. No parking restrictions but the space can fill up with day tripper and busses so an early start is recommended if you are overnighting.
A reservation is needed to stay at the Neil Colgan hut. Contact the Alpine Club of Canada
Staying at the Hut is 18$ for members. The guidebook mentions it has room for 24 comfortably but we counted only 16 mats albeit large ones.
Two good working propaine stoves. Lamps as well. New ventilation helps with the rooms tendency to steam up. Comfortable place when there are just three of you. Would be interesting to see full. Please leave the place cleaner than when you arrived.
