I found this in a creek and it has always been my favorite rock. I think it looks like a cross with a crown at the top. After lurking through this site I thought I would just make sure it wasn't anything other than a cool rock. Thanks!
In the Willamette Valley of Oregon, this would be a no-brainer.
Here it would be considered a net weight for fishing. Fairly common in my area. Almost always has grooves worn into the rock where attached with sinew, rawhide or rope made of horsehair and/or honeysuckle.
