Correct -- Silver Lake is still off limits. I took aerial photos of the place, and there's about 4 Poke-Os worth of climbing, maybe more.
Regarding choss, the Adirondacks has more than it's share. However, it's not all bad. I have fond memories of climbing the second pitch of Weekend Warrior with Dennis Luther, and the choss added an extra element of adventure and fun. Watching Flex Luther boulder over an unprotected 5.10 bulge was a special treat.
...Or The Cooler at Poke-O, jungle pulling and runout jamming up a corner (that's right, the jam crack flares in the back and doesn't take pro), and a lichen-covered wall with a wedged death torpedo on P3. All very memorable, perhaps more so because of the choss.
It would be fun to create a list of the "BEST of the Choss", or the "Chossiest Routes You Want To Do." Certainly these two routes are on my list.
