Mammoth Mountain & June Mountain Ski Areas UHF/VHF Systems
I posted information on the Mammoth Mountain and June Mountain Ski Areas radio systems on the data submission sticky thread. Those of you intereseted in these radio systems should take a look.
The following radio call sign and "code" information is probably not the type of information that would fit on the database. For those who visit Mammoth and want to figure out what they are hearing, the following should help you:

If I didn't pick up all the errors reading this infor in all 5's are Main Lodge base stations, all 6's are Canyon Lodge base stations, and all 7's are June Mountain base stations. At some point a number will probably be assigned to Eagle Lodge (near Chair 15) as construction on the permanent facility there may start in the next couple of years. Sorry the above is out of order as I had to insert this information from my notes and editing it to read correctly for this post is proving to be quite difficult.

Burrito Mammoth/June ski patrol uses this term for equipment loaded on a toboggan or sled which carriers the injured. The equipment carried is not known by the author, but probably gets wrapped up in a blanket.
MFA Malicious False Alarm * In reference to a reported injury/accident.
RGS Returned to Groomed Surface (Used by Mammoth Snowmobile Adventures)
RTB Returned to Boarding *
RTC Returned to Carpet * (The magic carpets are moving platforms to lift novice skiers up a very short and nearly flat run for instructional purposes)

That's about it except for a 4-5 page list of ski area terminology and slang which is used by lift maintenance and ski patrol personnel. I will not post it unless someone asks. I've gathered the definitions after careful listening over the 18 years I've lived within reception range of these ski areas.
Hope someone can use this information.
