||gmarkf couldn't find KW2805
Found only RM 1. Perhaps RM 2 and the station were destroyed in 2015 when road construction was completed on the road cut across the road. There are new-looking telephone poles, and the guy lines for one of them seem to be about where the station should be.
mloser's location photos for the station and RM 1 are reversed.

This looks like the same rock outcrop as in Ernmrk's photo, but no mark.
Location for Kink
It might have been where the excavation is for the telephone pole guy lines.
||mloser found KW2805
Like Ernmark said, this was a very easy find. There is no decent place to park so we parked at the base of the hill to the north and walked up--maybe .25 mile or so. When we approached the crest we realize that the road hadn't been widened there--they had only put in a central guardrail (this area was known for its horrible crashes for decades)as the hundred foot high cliff to the west and the 100 foot drop to the east must have been too much to deal with.
The marks were all totally visible as we walked up, and even the stub of the telephone pole remains.

||Ernmark found KW2805
Recovered in good condition during hunt with mloser - even though this station was reported to NGS as destroyed in 2001. The station & both RM's were exposed & easily found - this area is one of the few remaining areas of 11/15 which remain a 2-lane highway...it's possible that these disks were [i]expected[/i] to be destroyed during road improvements to the curve at this location, but ended up out of harm's way..
We searched for the AZ mark to no avail - medians are relatively modern..
Note - the area is locally known as Kinkora Heights...

- The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in July 1986.
- The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
- The Laplace correction was computed from DEFLEC99 derived deflections.
- The geoid height was determined by GEOID99.
