I found that claim. 3N16E Sec 26 SW & 27 SE. That's a long way from the LDMA camp I am talking about. That claim you gave is the area where Santafe is looking at.
Yeah that was the claim status on Santafe308's site. Sorry for the misunderstanding. I should have been clearer about which location it was.
For your Mer 21 T3N R15E Section 33 spot I found these:

________________________
The entire NW quarter section is private patented land meaning it's not prospectable. That pretty much covers the river in section 33. I guess the guy at the hardware store was right - the river is not claimed - but it is privately owned.
Without going to the trouble to map the claims I can tell you that there probably is no land open to claim in Section 33. You could get the claim locations from the county and check to see if there might be a sliver missed.
Keep looking, there is open unclaimed land out there. It's just not usually found next to a major road or known about by the guy at the hardware store. You can find those sweet spots that are open with enough research.
