went up from waterton townsite and alderson lake ,there is a little tricky loose downclimb coming back,which is actually un named at the highest pt. Buchanan is the first flat spot and has nothing tricky to get to,is 2406,I gps the other summit almost at the carthew height of 2590 shh. trr(the traverse from carthew saves extra elevation starting from cameron lake but is much trickier to downclimb from with loose rock etc. and rockbands)
Parked near the Rowe Lakes Parking lot, along the Akamina Parkway then up steep trees, then scree to the highpoint of Buchanan Ridge, then South East to lower summit of Buchanan Peak; returned the same route. Nice long ridge walk with Andrew Nugara.
Very nice day with a GMS group led by Ken McDermott. Did both Carthew and Buchanan--the only downer of the day was that the smoke was terrible; too bad, because these peaks have terrific views of other Waterton mountains, and south into Glacier!
Waterton Lakes National Park is just a great place to knock out some quick and easy scrambles when traveling back and forth across the border. I did three in two days in the summer of 2003. It is a quaint small park/town and this scramble is a great variation of one of the most acclaimed trails in North America (Carthew-Alderson). Cool Ptarmigans on the summit of Buchanan. It took me 8 hours to complete both of these scrambles, but it is a long day, I was moving fast and furious. Cheers!
