Exploring in the South Chilcotins around Griswold Pass as part of fieldwork for Robin's Thesis on moraine-dammed lakes. Completed a couter-intuitive traverse of Granite Creek, climbing Mount McClure.
For Robin McKillop's friends, the summers of 2004 and 2005 were abuzz with journeys in search of moraine-dammed lakes. He was conducting research for his Master's thesis on developing tools to assess hazards from outburst floods from moraine-dammed lakes (MDL). It was quite possibly the best topic I have ever seen since his worked required extensive field measurments and observations be taken on a large sample of lakes. This meant he spent most of the two summers traversing all over the Coast Mountains in search of MDL's

The happens to be a high concentration of MDL's in the South Chilcotins. In order to hit as many MDL's as possible, Robin had picked out a fairly circutuous route which headed up Slim Creek, and then completed a couple of traverses out towards Taseko Lake, and over to the Lord Glacier (A vintage overview photo of the Mount McClure and Granite Creek area is here). I had been in the area a few times over the previous year, and was keen to get out on a longer trip to the area in the summer. In my opinion the South Chilcotins is quite possibly the best area in the province for backpacking. Terrain is wide-open and broad alpine valleys are ringed by steep rugged mountains and icefields.

We started the trip from the standard approach up Slim Creek from the end of the Slim Creek Main logging Road. A trail follows along the north side of the Slim Creek Valley, and this route is fairly heavily used by snowmobile traffic in the winter. We followed along the main Slim Creek valley as far as the Leckie Pass turn-off. A short steep hike brought us to a group of lakes at the head of Leckie Creek where we set up a fantastic campsite. There was still a little time left in the day, and we spent the early evening scrambling up peaks 2417m an 2429m to...
