The "R" stone is from the 1921 Fryrear Road.
The 1/4 stone is from the 1869 GLO survey of T18S R12EWM Section 14.
The brass cap is self explanatory.
At a former house I had a C&GS mark in a concrete post that had been broken off by a blade. I repurposed it as a stepping stone to a hose bibb. I moved from that house 15 years ago; I wonder if the mark is still in place...
There is a house over on Wright Street (just north of Marconi Avenue) that has a USGS (Geologic Survey) benchmark in the concrete front porch.
They must've asked permission to set it there.

And here I thought you might actually be growing a garden in southern Deschutes County, due to that curiosity as to what could possibly be growing there I clicked on this thread, ha ha 🙂 Nothing survey related growing in my garden!
