This is a photo of a chart which is on the wall of Atlantic in KRIL (Rifle, CO). I was wondering what the big danger area is in the area of Mount of the Holy Cross. The A-N ranges are interesting too.

Wow, that's pretty cool. Definitely an old map. My guess is that the danger area is is for Camp Hale, where the 10th Mountain Division trained during WWII. This map could be that old as it doesn't include interstate highways.
 
What's with the "true north" compass rose just beneath the 15*E isogonic line?

Isn't it a given that the meridians are oriented to "true north":confused:.

Cool chart! Four course radios...wow! I remember those from my Sporty's videos:)

That's a good guess. You're probably right. I had forgotten about Camp Hale.

Hmmm.... maybe that's the way they did things in those days? :dunno:

Wish I had been able to get a picture of the whole chart including the legend.
 
"Danger Area"

I'm thinking that designation is no longer used on sectionals. I can't recall seeing those wordings. Right?
 
Danger areas are still used by ICAO, but the US calls them MOAs and ATCAAs (or restricted airspace if the "danger" merits that).
 
Does the chart on the wall have a legend at the bottom that says RESTRICTED?

That would date it to WWII, judging from a 1943 chart of Iowa that I've seen.

It does have some verbiage about what you are not supposed to use it for, lest you be punished. As I said, I should have also taken a picture of the legend.
 
Danger Area is likely warning of artillery fire around Camp Hale. R-2601 on current maps (Colorado Springs area) was called a Danger Area on the chart you show. R-2601 is used for a bombing range and artillery fire. Another Danger Area on the chart was the Buckley Bombing Range south of the current Buckley Air Base (east edge of Denver). Back in those days the CAA was apparently less excitable than the FAA over issues like artillery fire.

Camp Hale is correct. I have Denver sectionals from 1944, 1956, and 1966. By 1956 the boundaries of the "Danger Area" have been realigned a bit and redesignated Restricted Area R-482, the name is "Camp Hale", the activity is "Field Artillery and Mortar Firing." By 1966 it's gone. The "(Aux) AAF" in the image is shown as "Leadville AAF (Aux)" on my chart.
 
Can you imagine flying in the soup knowing there's granite nearby and trying to decipher your position be listening to tones in your headset?? Amazing.

Well, yes I can, it doesn't seem all that difficult.
 
Gee, I was hoping it was an early wave window for gliders.:D
 
I was up in the "danger area" a week ago, skiing at Ski Cooper. And took a lesson from my favorite instructor, one John Gordon, former 10th Mountain Division. Gordon is a member of J.O.E.S., and is an expert at teaching the conservation of energy on skiis.
