Slitherlink Snub Square Mystery Cache

Before creating this puzzle, I hadn't tried this tiling. The combination of squares and triangles made for some interesting patterns.

In the Snub Square tiling, the shapes that appear are squares and triangles.

To work out the location of this cache, you need to do the following:

1. Solve the puzzle below (see the cache listing for Slitherlink Boot Camp for the rules about how to solve Slitherlink puzzles).
2. Locate the letters a through to t in the puzzle (l and o are omitted). For each letter, its numeric value is the number of lines around the cell.

The original cache location was S 43 31.ABC E 172 33.DEF, where:

A = a + b + c
B = d + e + f
C = g + h + i
D = j + k + m
E = n + p + q
F = r + s + t

The checksum for A to F is 29.

In December 2022 the cache was replaced in a new location (add 0.008 to the South minutes and Subtract 0.011 from the East minutes).

The cache is a pill bottle attached to a cable tie a little above head height. Look for the small tree with multiple trunks.
