Poetry. Over 25 years in the making, HEADWATERS: POEMS & FIELD NOTES shares a seasoned naturalist's perspective on wilderness and imagination from time spent around the mountains and rivers of the Pacific Northwest. Weisberg's poetry grows out of specific images and distinct moments gathered from the natural world. It celebrates green and misty landscapes and the wilderness they hold. The poems are an invitation to walk alongside a perceptive observer on rambles in the mountains, runs down the river and ruminations in desert canyons, investigating the ties that bind people and place.
