Ask someone on the technical staff for instructions on how to obtain permission. During bad weather conditions, driving has to be reduced to an absolute minimum. Please return to the Lodge while conditions still allow driving back safely. After a snowstorm, maintenance personnel will, first of all, clean the road to the telescopes. DO NOT go to the telescopes before the road has been cleared.
Ice is as much of a hazard as snow, or more.
Watch out for slippery roads. Like at any Observatory, there are areas of potential danger on the mountain. By all means, avoid climbing on telescopes, structures, domes or any other potentially dangerous places. If this is absolutely necessary for your work or to satisfy reasonable and normal curiosity, ask someone on the technical crew to go with you and follow instructions. Unless you are required to be part of the operation of mounting or dismounting an instrument or parts of instruments or telescopes, you should observe such actions carried out by the technical crew from a safe distance.
