Stump the Chump

[Jim Hardin]

I was musing with a chart around some of my old stomping grounds and came across map symbols that I don't recall seeing before... Having flown there it is even more perplexing that I do not recall anything that jumps out of that area

What I am referring to are the tick marks around the BEARCE (7M3) airport west of Hot Springs.

My thinking is that they are bluffs/cliffs but just don't really know.

I don't see anything on the chart legend, but I think I may have a more exhaustive legend over in my hangar.

I'm headed over shortly - I'll let you know what I find.

Maybe it's these guys? Look out!

If you are talking about the circle segment that your green dot is on, then that is an exclusion for airspace in the MOA 1500 foot and below for the airport.

Here's the guide I had at the hangar:



Depressions?

No, that's actually Class E to the surface. Has nothing to do with MOA which that airport is not in. It's for IFR protection from VFR traffic in low weather conditions. They don't want any VFR aircraft making takeoffs and landings with Class G minimums (1 mile, clear of clouds).

PS: The green dot is iFly GPS depiction for VFR weather.

EDIT: Yes, you are correct. We're looking at two different airports and two different green dots.

Sorry I should have stressed it is the topographical symbol that baffles me.

I know the depression symbol, tick marks on the inside, toward the lower ground. But these are on the outside and the ground enclosed is higher plus I do not recall ever seeing that symbol used before.

I fly over that area a time or two a year on my way to KORK and that area a bit south of 7M3 looks to be where there is a pretty deep and narrow valley. Maybe that's the 'depression'?

[FastEddieB]

It looks like the direction oh the hatch marks identifies rising or lowering terrain, i.e. mound or depression.

[TimTaylor]

Since there are a few peaks marked within, I would say they are mounds.

Another clue, one is named Mount Ida.

Ida know about that.
