International EarthCache Day 2024

This weekend, Dale and I decided to participate in International EarchCache Day. For 20 years, EarthCaches have encouraged geocachers to explore and celebrate the extraordinary geologic features of our planet. EarthCaches do not have physical containers. Instead, they take you to a unique geological feature. To earn this cache, you study your surroundings, then answer the questions listed in the cache description.



We chose a close cache in an area I've been wondering about for a while. There's a rock quarry along the Willamette River just off the "Beltline" highway. I first heard about this area in a rock-painting group because there are river rocks there in many sizes that are smooth, making them excellent for painting. After a couple tries, we found our way to the river. Unfortunately, we weren't in a 4 wheel drive car, so had to get creative about parking. All the other vehicles in the area were SUVs and pick-ups. Our little VW beetle doesn't have the proper clearance to traverse the rocks.



We learned about how the river constantly carries rocks from the local mountains downriver. They get deposited here. The rocks flow when the river runs high; they get deposited as the water recedes. 

Wood snags also get deposited here under the highway.



To earn this cache, we needed to examine the various sizes of rock, gravel, and sand and take some photos. Then we were to estimate the distance from the current shoreline to the concrete freeway support there in the middle of the river. Finally, you let the cache owner how you might use these various sizes of rock around your home.



This isn't an official park in Eugene, but I've often seen folks sunning themselves, dogs splashing in the water, and people fishing.

There were lots of birds flying, singing, and dive-bombing under the bridge and at the water's edge.



An entire chorus!






On the way back to the car, I found



A heart-shaped rock, of course!
