Elk Pass is a fine place to climb ice if you want to get away from the crowds, don't mind lugging all your gear roughly 12 miles round-trip, and enjoy arriving back at your car exhausted in the dark. And even then, it might not be worth it...
Elk Pass is a secluded pass between Nippletop and Colvin. Along the Colvin flank, you'll find a 120+ foot ice flow with several lines possible in the NEI 4 range. Probably twice as wide as Positive Reinforcement.
The top of the flow provides a nice view of Nippletop slide.
It may be possible to rap with one 60 meter rope from certain cliffside "trees," but I'd take two ropes.
Take the Ausable Club road to the trail that heads down Elk Pass. Where the trail veers hard left to ascend Nippletop, continue straight, crossing the pond (see beta pic), and follow the pond's drainage. 20 minutes or so and you should see the ice on your right.
