Thanks for the information. No wonder I was clueless about this... as I think I mentioned to you, the road beyond Heather Meadows was still blocked by snow when I visited in late July, so I didn't really pay much attention to anything beyond it. MUST RETURN!!!
But wait, there's more! Artist Point and The Ptarmagin Ridge trail share the same parking area as the Chain Lakes trail. Ptarmagin ridge will take you right to Coleman Pinnacle. That trail is a little more difficult than most though. Artist Point is on the other end of the spectrum as far as ease is concerned. It is a short loop with great views of Shuksan and Baker and a bunch of nice tarns.
I had seen the trailhead for Lake Ann on the way up to the Artist Point trailhead. In the interest of disclosure this is not the same Lake Ann that I visited recently. The lake that I went to is off of highway 20 near Rainy Pass and the aptly named Rainy Lake. I would however like to visit the Lake Ann that is close to Mt. Baker sometime in the future as the trail does continue on to an area near the Lower Curtis Glacier. Here's a link with some trails that can be accessed from the Mt. Baker Highway: [link] There are other areas on that page as well for your review.
