buddy,
That's a beautiful area in general. Mostly open woods and easy bushwhacking. I know a little about the area. I've bushwhacked from the Lindsey approach up Wyman via the long NE ridge. I've also been up Spotted along the ridge from the Boquet. I have never been on the SE face of Spotted, but it has always looked interesting to me; tell us what you find!
Lindsey Brook approach trail is flooded by beavers, so it's closed in summer; might be well frozen now, but I don't know. The Lindsey drainage comes very close to the S Fork Boquet drainage at one point; they're only separated by a very narrow strip of land. If you're going to approach that area when things are not frozen, you might consider one of the Boquet approaches. I can think of three Boquet options to get to the SE face of Spotted:
1. Follow the S fork of the Boquet from where it crosses rte 73. There is some parking there, and there is a fish stocking trail along the L (NW) bank of the river for a little ways. After the fish stocking trail runs out, cross the river and continue upstream on the R (SE) bank. A little furher along, a good trail joins the river on that side (I think this trail is a private trail onto state land from the Underwood Club). That trail continues to the point where the river makes it abrupt turn to the NW. The trail ends there at a very attractive maintained campsite on a knoll by the river. From there, you could bushwhack SW into the valley alongside Spotted.
2. Take the "Hunters herd path" that starts along the N fork, past Lillypad Pond to where it joins the S fork; then bushwhack downstream SE along the S fork and around to the SE side of the Spotted ridge (I have been through there; the going is not too bad).
3. Again from the Hunters herd path, angle up onto the ridge to the small prominence (686m) called Elizabethtown #4 on some maps. Then traverse onto the SE face of Spotted.
I think Jayne Bouder and/or Rich Crammond have led some Glens Falls ADK groups up the SE face of spotted in recent years. Contact information for them can be found at <http://www.adk-gfs.org/outings.html>, as they continue to lead chapter outings. I'm sure they would know a bunch more about the area.
Good luck!
