In Lake, River, Mountain, Mark B. Hamilton follows the Lewis and Clark route on a physical journey paddling a kayak westward on the Missouri River, across the Great Plains. Immersed in a natural world, the environment is ever-present. The weather, the water, the habitats and fauna, and the lands of Native Americans all merge to conjoin or confront, as they in turn influence beliefs, emotions, and hopes for the future. Hamilton crafts poems both intimate and sweeping, with time and history merging into a confluence of friendship, family, and finding one's place in the world.
