Started out intending to do Marshall, Iroquois, and Algonquin from the Upper works trailhead. There are supposedly two paths up to Marshall. The one we intended to take was either very poorly marked or not marked at all. The other trail (I believe, please double-check before making plans) is marked as Cold Brook Trailhead, on the northern end of Lake Colden near the DEC outpost.

They have been having problems with a bear at the Lake Colden lean-to. The bears in this region know how to chew through the Bear Vault canisters and our canister had to be stored inside another large canister at the outpost. We heard snapping sticks outside our tent that we assumed to be the bear and had to make noise to get it to leave. It won't hurt anyone but it is an aggressive bear and had been sprayed by the ranger as it walked toward our campsite less than an hour before we went to sleep.

We climbed Algonquin from Lake Colden - beautiful views - and skipped Iroquois due to a late start, although it's only about a mile from the peak of Algonquin. The 2 ish mile trail up to Algonquin is steep, rocky, and muddy in spots, but gorgeous and worth the climb.
