This cache is located in a unusual wetland-style park in the north end of Portland's Pearl District.
The History of the Lake Beneath Tanner Springs Park
What is now known as the Pearl District was once a wetland and lake fed by streams that flowed down from the nearby hills in southwest Portland. These wooded hillsides provided a natural filter for the streams, cleansing the water as it made its way to the Willamette River. The springs from Tanner Creek, named for the tannery built by pioneer Daniel Lownsdale in the 1860s, flowed into the shallow basin of Couch Lake, now the area surrounding Tanner Springs Park. As the population of Portland grew in the late 19th century, Tanner Creek was rerouted through an underground system of pipes to the Willamette River. The lake and the surrounding wetland were eventually filled to make way for warehouses and rail yards which in turn were replaced by residences, shops, and public spaces. Today, the park sits about 20 feet above the former lake surface.
The above information appears on the Portland Parks and Recreation website. Similar information appears on the inner north side of the shelter for the NW 10th and Marshall street car stop.
The Cache Location
The cache container is hovering just above the “lake”, somewhat north of the halfway point of the metal path. Please don’t drop the cache in the lake: geocaches aren’t native to the fish habitat and the container isn’t waterproof. BYOP!
*** I finally adjusted the coordinates. However, between the metal rails and the high-voltage lines, it's hard to get an accurate GPS reading, so if you're searching near the street, you're in the wrong place. Since enough people have had trouble finding the cache (mostly because it gets put back in the wrong place), I've upped the difficulty rating a half point. ***
Congratulations to Scubasonic for the FTF!
