The leaves are alternate, oblonceolate or narrowly ovate, two to five inches long, and usually sharp-pointed. The flowers appear before or with the leaves, on short leafy shoots, males are five centimeters long, and the females are eight centimeters long (Pojar & MacKinnon 1994). The bark is smooth, slightly furrowed, and scaly.
- Deschutes River (Wikipedia)
The Deschutes River (/dəˈʃuːts/ də-SHOOTS) in central Oregon is a major tributary of the Columbia River. The river provides much of the drainage on the eastern side of the Cascade Range in Oregon, gathering many of the tributaries that descend from the drier, eastern flank of the mountains. The Deschutes provided an important route to and from the Columbia for Native Americans for thousands of years, and then in the 19th century for pioneers on the Oregon Trail. The river flows mostly through rugged and arid country, and its valley provides a cultural heart for central Oregon. Today the river supplies water for irrigation and is popular in the summer for whitewater rafting and fishing.
