Pompelly Pillar Two Medicine Lake - Glacier Park The End of the Road . . . entering Glacier Park at Two Medicine was, appropriately enough, Two Medicine Lake and the pointed Pompelly Pillar marking the gateway to unspoiled wilderness. A boat ride up the lake and short walk to Twin Falls was not afforded us in the meager time allowed for this park entrance. We had many miles to go, missions to complete and other waterfalls to see.
