“A quick way to the top of Mt. Lincoln from Montgomery Reservoir.”
— Jacob Winey
Park at the east side of Montgomery Reservoir and head up the slope to the south west. You'll quickly get to a steep gully with a few ice falls. The ice is easy to go around, but the gullies may require some boot packing to get up. After that, you're at the base of the amphitheater. Follow this to the west, and you'll quickly see some steep lines on the looker's right at the end of the amphitheater. Go left of that face, up a more mellow slope. This area is just the right angle to skin up without switchbacks. Gaining elevation here is pretty quick, and before you know it, you'll be heading up the summit cone for Lincoln.
From the top of Lincoln, you have a lot of options. There's the Russian Couloir to the south, you can ski back down the amphitheater to the east, check out the couloirs on the north face, or continue on to Cameron and Democrat to the west.
