Monday, November 14, 2016 7:00 PM - 8:00 PM

Between 15,000 and 18,000 years ago, a series of momentous floods crashed through the Pacific Northwest, reaching heights of up to 400 feet where Portland lies today and carving the landscape of the Columbia Gorge and Willamette Valley.

Geologist and gifted speaker Scott Burns will focus on the incredible story of J Harlen Bretz’s discovery of the Ice Age floods and the pioneering research that Bretz used to prove his discovery to the world. Burns will also discuss the floods’ effect on the formation of 16,000 square miles of Pacific Northwest terrain, from eastern Washington to Astoria and the Willamette Valley.  Whether or not you’re a geology buff, you’ll be glad you joined us for this fascinating and humorous presentation about our region’s natural history.

Scott Burns is a Professor Emeritus of Geology and Past-Chair of the Dept. of Geology at Portland State University. He has been teaching for 44 years, with past positions in Switzerland, New Zealand, Washington, Colorado and Louisiana.  Scott specializes in environmental and engineering geology, geomorphology, soils, terroir and Quaternary geology.

Clackamas County Chapter Meeting:Northwest Plant Evaluations: Plant trials and the results - Neil Bell, Community Horticulturist, OSU Extension

Mon, 10/31/2016 - 5:12am
Monday, October 10, 2016 7:00 PM - 8:00 PM

In 2000, Neil Bell began research to identify a palette of shrubs suitable for low-input, un-irrigated landscapes in the Willamette Valley. Since 2000, he has conducted many studies of landscape plants for drought tolerance and cold hardiness, collaborating with Heather Stoven.

Studies on Ceanothus, Halimium, Hebe and Grevillea have concluded and results continue to inform the nursery industry and home gardeners in plant selection.  Neil is currently evaluating 75 selections of Arctostaphylos (Manzanitas).

Neil’s method for evaluation is harsh by home garden standards—plants are not watered, sprayed or pruned for the duration; they are rated for growth, flowering and hardiness. The goal is to provide information on plants suitable for “low-input” landscapes in the Willamette Valley and other areas west of the Cascade Mountains.

Since 2000, Neil Bell has overseen the Community Horticulture program in Marion County and Polk County, which includes the Master Gardener program.  Among his significant contributions to the Statewide Master Gardener Program are training on diagnosis of plant problems and pruning of ornamental plants. He has co-authored publications on water-efficient landscape plants, soil amendment and mulch use. Neil lives and gardens with his family on 5 acres west of Monmouth.
