K so I did recon from the
ahem source of the pink flag pic. I think it might actually be legit now. Orange is usually for utilities, and they've got an orange line indicating a direction there.
Additionally, the picture with the orange triangle and the symbol to the right of the 13 usually represents a tool like an automatic level, which they use to measure elevations. They're probably indicating that they're using a 13ft high plane in reference to a benchmark (metal thing in the ground with a known exact location and elevation). Surveyors will walk around with a measuring stick and measure the difference off of said plane to get elevation data and other stuff.

But seriously RMC leaked their frigging earlier projects when they wanted to hire a surveyor in all of the regions they ended up building something for the 2016 season. Continuous total lack of concealment on their part. B&M was least smart enough to have people stop measuring brakes and crap at 8:30AM on random mornings for the Rougarou conversion and were very subtle about it.
