I’m a volunteer with CSAR (Clackamas Search & Rescue) and we are involved with a “cold case” from the 1980s.
The 40+ year-old files refer to a road as, “S57G” and it says it is about 4.5 miles southeast of the Ripplebrook RS. Can anyone confirm that old MHNF roads always started with an “S”? That vaguely feels familiar. A map photo would help.
THEN, what does the “G” mean? Could spurs have had letters?
We appreciate any help finding this location.
Thanks,
Jerry
If you look at the map layers on our map page here:

This shows the district map from 1972 centered on the S57 road (which is now just road 57). You can see most of the old numberings and it does appear as if all the roads were prefixed with an S, which I'm guessing means "South". It does not show numbering for spur roads but I'm guessing you are correct - the G indicates a spur road off the S57 road. I'm not sure how you would figure out which spur road it is. 4.5 miles SE of Ripplebrook puts it somewhere around Oak Grove Butte it looks like.
