hence the not very transmissibleGeneralizations, other experts say more than 5 or 10 minutes. There have also been documented cases of transmission outdoors (dig throgh the COVID19 and ski travel posts), even where the spreader and targets were moving around, walking together etc.. .. Lift corrals tend to be surrounded by buildings on 3 sides and the mountain on the other, out of the wind. Out on the mountain skiing risk is trivial but not impossible.
at the areas I ski, the lift lines are not protected by surrounding structures from wind and sun
of course there is going to be social distancing in the lift lines
the real issue for operators is skier spacing/conduct in the lodge
