Carthew-Alderson Lakes

The trail starts out with a grueling ascent, switchbacking relentlessly above Cameron Lake.
You are sustained by the odd lookout, and the knowledge that this toughest part will be brief.
Before long, the trail arrives at strangely-named Summit Lake. From here, the trail diverges.
One way will cross the international border, then parallel East until meeting Upper Waterton Lake.
We will be turning north instead, and continuing to climb - this up steadily along the side of Mount Carthew.

Pretty trail with colourful rocks and flowers.

The high point of this trail is known as Carthew Summit - though it is merely a pass and nearby high point.
Tucked under Mount Carthew and connected down a long ridge to Mount Alderson, this pass looks down one valley
most of the way down to Waterton townsite, and the other a gread distance across to the American peaks.
Hiking just above the pass brings you to a small point with a great vantage. This is also where one would pass by to continue on to the summit of Mount Carthew - and easy scramble.

From this high point of the trip, it's a long easy cruise downhill backto Waterton Townsite.
Along the way, you pass the two Carthew Lakes, a few tarns, and a lovely deep blue Aldeson Lake.
The last few kilometres are completely treebound and uninteresting, but at the end of the hike, going downhill, you can zip through.

The Canadian Rockies, being largely a series of thrust faults of varying sizes, contain almost no volcanics, except down here in Waterton.

After the hike, we met up with Kelty and a friend who had remained in the townsite, and reorganized for the ride home. Kelty, Garnet, and I stopped off for a little more geological fun before heading back - see Page 3.
