NPSO 2016 Annual Meeting
Natural History and Points of Interest
The McKenzie WatershedEncompassing 1,248 square miles, the McKenzie Watershed lies within Linn and Lane counties. Ecoregions include High Cascades, Western Cascades and the Willamette Valley with elevations from 10,358 feet at South Sister to 373 feet at the confluence of the McKenzie and Willamette Rivers. Maps of the Watershed’s boundaries, elevations, and drainage patterns are provided courtesy of the McKenzie Watershed Council (2000).
McKenzie River OriginsThe McKenzie River flows westward from the high Cascades. The river’s primary source is snow melt from direct runoff and from porous lava, which can retain water for several years.
The water in Clear Lake is so clear that a prehistoric forest of snags can still be seen on the bottom (Sullivan, 2000). Clear Lake is recognized as the McKenzie River’s source, but actually it is the place where we start to name it the McKenzie River.
One and a half miles south of Clear Lake the river surges over a cataract that drops 73 feet. Natives called the falls Sahalie, a Chinook jargon word meaning “high.”
Expect to see spectacular views, lava fields, roaring waterfalls, white water, cathedral forests, and the scars of past forest fires.
Fires in the Western Oregon Cascades are regular occurrences. Charred rings in old trees remind us that fire visits on average every 70 years on the wetter west side of the Cascades. Recently it seems wildfires are more frequent. Lightning strike fire is a major natural disturbance.
FloraHerm Fitz (1983), McKenzie valley resident, ecologist, and former NPSO State President, has said that unusual plant adaptations occur in the McKenzie River Valley. Some plants are more typical of adjacent regions to the north, south, east, and west and many are disjunct from their main populations. Gentiana newberryi is a plant more typically found in flora to the south.
