Saturday, July 10th, 8:00 am
Field Trip: Iron Mountain and Cone Peak Hike the Iron Mountain - Cone Peak loop, identifying wildflowers in this botanical hotspot. Over 200 species of vascular plants have been recorded across this botanically rich trail west of Santiam Pass. Wildflowers of the Western Cascades (Ross and Chambers, 1988) focuses on the flora of this area. A delightful post about the area by Tanya Harvey can be read here: Tanya’s plant lists are here: The Iron Mt. list is under the “Santiam” heading.

The loop is about 5 miles through moderately difficult terrain and it takes all day since we go so slowly looking at all the flowers. It is about a 1,000 ft. elevation gain, mostly in the first 1/3 of the hike. We will return in the late afternoon. Bring a lunch and water, dress for the weather, and wear sturdy shoes. Location: meet at the OSU Wilkinson Hall parking lot southwest of the Beanery at 26th and Monroe. Vaccinations or masks required for carpooling. For more information and to RSVP, contact Dan: 541-752-8860 or

Field Trip: Upper Elk Meadows Alan Curtis leads us to a mixture of coniferous forests and open wetlands with a great variety of herbaceous plants, including an unusual one, Umpqua frasera (syn. Swertia umpquaensis). The old-growth forest is composed primarily of Douglas-fir and Pacific silver fir. Vine maple and Sitka alder are common on the edges of the wetlands. Nine springs arise in the wetlands. Elevation of the area ranges from 4000 ft. to 4385 ft. Wear boots and bring lunch, water, and sun protection. Meet at the South Eugene High School parking lot at the corner of 19th Ave. and Patterson St. at 10:00 am. Limited to 8 participants. Please register here.

Field Trip: Oregon Dunes Restoration Hike the John Dellenback Trail with Siuslaw National Forest botanist Armand Rebishke and see what the Siuslaw National Forest is up to with dunes restoration. This area is a “preserve the best” unit, meaning it has an abundance of native dunes plants – adapted to open sand conditions reminiscent of historic dunes conditions before the planting and expansion of European beachgrass, brooms, and other invasive species. We’ll see seashore bluegrass, sand fescue, and bearberry plant associations among other native dunes species. The sand boundary was treated during late summer 2020 by cutting and wiping Scotch broom, spraying European beachgrass, and cutting small pines. Meet at South Eugene High School east parking lot (19th and Patterson St.) at 8:00 am to carpool or at Dellenback Trail at 10:30 am. (To get to John Dellenback Dunes Trailhead go to the junction of Hwy 101 and 38 in Reedsport and turn south on Hwy 101. Go about 11 miles. Turn west toward Eel Creek Campground and follow road to the end for trailhead parking.) Drivers will need a parking pass. Hike will be 3-4 miles round trip (it is an out and back trail). If you want to continue on to the ocean, the round trip is 5.4 miles. Sand dunes hiking can be strenuous, windy, and chilly. Bring water, lunch, and sun coverage. Sign up here.
