Interesting comparisons. Bears, while present in some of our mountain ranges, are not the problem that they can be in Alaska. One reason we respond quickly at night is that our victims are often dehydrated, or at least rather thirsty, so time tends to be critical.

Some years ago, I was on Denali during June. We had all sorts of equipment, but no need for any kind of light - perpetual daylight at that latitude and altitude.

There seemed to be a tendency for many of our searches for the typical overdue party seemed to resolve around dawn the following day. More and more we tended to send out parties that would get into the search area and hang out, perhaps even bivvying there. When the sun rose, we could easily find our victims as visibility increased and everyone started moving around.

Different techniques for different circumstances.....
