and mountain biking. For aquatic adventures, students can cliff jump or boat at the Snake River. Farther out, white-river rafting, downhill skiing, and hiking in the nearby foothills of the Rocky Mountains are available. WSU formerly operated its own alpine ski area in Idaho, the North-South Ski Bowl, which was sold in the early 1980s.
=== Arboretum and Botanical Garden ===
The WSU Arboretum Committee continues to develop an Arboretum and Botanical Garden on a hilltop adjacent to the Lewis Alumni Center. In addition, about 95 acres (38 ha) on the east edge of campus has been identified for a more expansive Arboretum and Botanical Garden, including a wildlife center. Students interested in contributing to the development of the WSU Arboretum are working with the Native Plant & Landscape Restoration Nursery to help establish tree plantings, future habitat restoration sites, or native plant displays that may be part of a campus green belt design.
