Mont Tremblant

[KC1AML]

I saw the attached sign near the summit of Mont Tremblant today. Does anyone know what channel 1A is? Could it be referring to marine channel 1A?

These phone numbers belong to the ski resort. Channel 1A is probably an internal talkgroup that the workers on the ski resort use.
Referring to this : http://www.radioreference.com/apps/db/?sid=6380
Talkgroup 1-A is for the panoramic gondola.
