I'm wondering if anyone can decipher a few terms on my C&S Valuation map.

What would the following be:
1. This type of designation is where the line crossed a stream:
1803+04(small o raised up here) 12' X 12' Box 18' -
-my guess is a culvert?
-sometimes there is a "W" before the "Box"
-others spots of "Open Box" or "Stone Box" or "Wood Box"

2. Curves
What does P.T. and P.C. mean?-related to curves-PT is at the beginning of the curve and PC at the end

3. A triangle shape is used in several spots too.

4. Rock walls have dimensions such as 1 X 5 X 52.  Is that width, height, length?

5. At a water tank (Tunnel Gulch) it says 1776+22 (small raised o) 15 W. Tank
What are the numbers referring to?

6. Signs
Occasionally, a sign is listed.  Sign "W" I assumed would be for whistle?
There are spots listed for Property Sign.  What would that sign be for?
What would a Section Post be?

Thanks!
