Sandy River Delta

“I try to give people a different way of looking at their surroundings.” – Maya Lin

Site Features

When you enter the restored forest ecosystem at Sandy River Delta, you’ll encounter an elliptical bird blind, which embodies Confluence Project’s commitment to sustainability and ecologically aware artistry. Stroll up a gently curving 150-foot ramp to the bird blind, constructed of sustainably harvested, durable black locust wood. From this quiet spot, you can view birds and wildlife that inhabit the area today as you learn about the flora and fauna–some of which are now extinct, endangered or threatened–that existed here 200 years ago. The artwork serves as a lasting reminder of the impact humans have had on the environment and a model for a new way to envision the connection between people and the natural world.

Confluence has developed a printable field guide to the SRD, designed for kids but usable for all ages, that you can download here.

1– Bird Blind

A 1.2-mile trail, built primarily by volunteers, leads from the parking lot to Maya Lin’s elliptical bird blind. The wood used to build the bird blind comes from the black locust tree, a long-lasting, sustainable hardwood that is considered invasive in the Northwest. Using locally harvested black locust for this project supports efforts to eradicate the tree from native forests and reinforces the Confluence Project’s goal of promoting sustainability. The vertical wooden slats of the bird blind are inscribed with the name and current status of each of the 134 species Lewis and Clark noted on their westward journey.


The site was formally dedicated August 23, 2008, with more than 500 people attending.

Project Partners

The Sandy River Delta site was built by James E. John Construction, of Vancouver, and Krekow Jennings Inc., of Seattle. Other key partners include the Oregon Department of Transportation, which built a new, safer deceleration lane at Exit 18 on westbound Interstate 84; the U.S. Forest Service, who owns the land at the site; and the Oregon National Guard, who built a new parking lot at the site as part of a training mission.

Directions to Sandy River Delta

The Sandy River Delta is just north of I-84 off Exit 18. Driving east, exit the freeway and turn right at the T, go under the overpass and enter the park at the sign. If you’re driving west on I-84, take Exit 18 and take an immediate right. At the parking lot, look for the gravel path marked “Confluence.” Follow the path for 1.2 miles to reach the Bird Blind.

Please be aware that during high winds or after high winds there is a danger of trees or tree limbs falling, it is a good idea to avoid the area during these times. And if you happen to see a tree that looks in danger of falling or losing limbs, please let us know.
