Final Notes on Second Page
Beginning of 3 Mile Subdivision
Brass Cap ¼ Corner Between
Sec 34 T8S, R11E WM &
Sec 3 T9S, R11E WM
Problem:
Missing GLO records to show
when this brass cap was placed.
Broken chain of evidence.
Assume corner remonumentation was done
around the 1920’s? Lincoln E.
Wilkes worked in adjacent
township in 1918, but no plat
filed for these townships.
Records may be with state BLM
office? Existing monuments not
set firmly in ground.
Need to Prove Correct Locations
for Existing Brass Cap ¼ Corners
My Solution:
Use Original GLO notes for 3 mile rule
subdivision of sections to find scribed stone
monuments for the nine interior 1/16 corners
within each section.
If interior monuments agree with predicted
positions from suspect brass caps on exterior
boundary of section accept unknown sourced
brass caps as accurate.
Sample 1/16 Corner Breakdown of Section
Note:
Mounds are NOT
corner monuments.
Mounds constructed
ALONGSIDE scribed
stone monuments in
cardinal directions
(N,S,E,or W).
Scribing normally on
flat face on north side
of stone monument.
Occasionally on bottom
of stone, may be
partially buried in
ground.
