Field Trip: Iron Mountain and Cone Peak 
Leaders: Dan Luoma & Joyce Eberhart
We will 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: A Rainbow of Colors at Cone Peak and Iron Mountain. Tanya’s plant list is here:
The loop is about five miles through moderately difficult terrain and will take all day since we will walk slowly looking at so many flowers. There is about a 1,000-foot elevation gain, mostly in the first one-third of the hike. Bring lunch and water, dress for the weather, and wear sturdy shoes (there may still be snow drifts). 
We will meet at the Oregon State University, Wilkinson Hall parking lot (44.5692746, -123.2810976) southwest of Allan's Coffee and Tea at 26th and Monroe. For more information, contact Dan: Please leave furry friends at home.

Saturday, July 27, 10:00 AM
Field Trip: Whaleshead - Indian Sands Hike 
Leader: Olivia Dethlefsen
Location: Whaleshead Beach (Upper parking lot)
We will gather at the upper parking lot for Whaleshead Beach (At the top of the hill, not the parking near the beach). The hike will begin at 10:15 and is expected to take at least two to three hours depending on how far participants want to go. This will be a strenuous hike of about three to four miles, with considerable elevation change.
The plan is to take the coast trail north to the vicinity of a pullout between Whalehead Beach and the large Indian Sands parking lot. In this area, we will find orange bush monkeyflower near the northern edge of their range, expected to be blooming in late July. 
At this point we have the option of doing a longer hike all the way to the bluffs at Indian Sands, which would be around six miles total, increasing the hiking time to five or six hours, or we can turn back here depending on group interest. There is also the option to take a short but steep walk and see the sea bluffs on the tip of Whaleshead itself.
Please be aware that there may be poison oak in places along the trail. Usually this trail is well maintained, so it is not an issue except when leaving the path.
To sign up, or with any questions, please email Olivia at
