Tonight, March 22 in Macky Auditorium, the Boulder Philharmonic will perform Ghosts of the Grasslands by composer Steven Heitzeg, a work that celebrates the life of the American prairie. Prepare for the concert with an easy morning hike to learn about the plants and animals of our native grasslands, and how they have changed since the first pioneers arrived in Boulder. Open Space naturalist Dave Sutherland will take you to a prairie dog town just south of Boulder to observe day-to-day life, and see how prairie dogs are an important part of the grassland ecosystem. Dress for the weather: it might be cool and windy. Meet at Marshall Mesa Trailhead, near the junction of Highway 93 and Eldorado Springs Drive.
