Thanks for these maps:
For 1. Is the arc the one which faces north with the
"HUA" of CHIHUAHUA under it and the "S" of TEXAS above
it? Or the tighter one facing south just to the right
of it? Or the real wide one facing northeast to the
right of that?
2. Arc is the wide curve facing WSW where the other
stream comes in?
3. Arc faces NNE to the right of "CO" of PRESIDIO CO?
Or facing S/SSW just below BM 2562?
4. I remember seeing this before - the 1/4 circle
facing SE.
Also - Is Beaver Island somewhere in this vicinity?
Is this still an island (if it is in the area, did
rechannelization have an effect?)?
