I chose to take the day to locate a few remote monuments in between the rains we are gladly experiencing this winter.
This is an area on the northern edge of the fire that devastated an 83mi perimeter in Cass and Marion Counties.
From here Black Cypress passes thru the center of the burned farm and timber land.
I have visited this site many times since 1974 when I first had reason to locate it and today was time to do so with a static session.
It is the NWC of an associate's land that has placed Carsonite marking post beside all his monuments making them easy to find.
A few views to the North
The pine knot laying to the side was found by Rotan who set the pipe.
A view to the West
This location is the beginning of a survey to relocate monuments spread across the burned area.
You obtain reliable GPS results from such timbered areas?
YES,
especially when there are no evergreen trees and receiving an ample supply of signals. Even among evergreens I have had success when there are enough sats n the sky and I have received good signals without interference. Occupation times are usually from 5mins to over an hour taking note of PDOP, Range and adjusting the antenna height.
Some days are better than others under canopy. Dry days are better. Gusty wet days with leaves can be fruitless. It can all be turned around to useable with a 12ft antenna height to boost the signal.
That set up had 11 sats in view with 8 sats with clean signal for a period of 39mins with an adjusted position 95% reliability of 0.006
With three units, I have two sitting on control points about 3mi from each other that are in locations that have a lot of sky. I use one as a rover.
I will be back down there to locate something I found after I had packed up and was ready to leave for the day. It will need a much longer session.

You know it made complete sense to me, once I saw the fifth photo, that you would probably leave the Trimble set up as a base on the two section pole with tripod, and then maybe take off with a 7' Castaway rod attached to an Abu Garcia 5500 rover.
This is what i'm seeing.
Good stuff. I enjoyed working on Black Cypress in my time in Marion County. It definitely earned it's name. 🙂
Did you have an opportunity to see the albino alligator on you project. It makes its home near Big Cypress.
When I mapped my 6 miles of the river, I saw one snake and could walk across it. It was 112 degrees. No gators. Would have liked to have seen it. I was in Berea.
Should have brought a few duck decoys...b/c that looks like a good mallard and wood duck hole.
