- Why are caves different temperatures?
And then the second part of that
is what is average and what cave
is the coldest
and what cave is the hottest?
That's a lot of questions by the way.
(rangers laughing)
- It depends where the cave is located.
So it's going to be
the mean annual temperature
of the location of the cave.
So around here it's 54, 55 degrees.
And if we go to the tropics,
I'm from Puerto Rico so if we go down there
the caves are going to be warmer
because the mean annual temperature can be,
for the cave, in the 70s.
So it's gonna be hotter and you don't need
as many clothes, so it depends.
If you're in the desert,
the cave is gonna be warmer so.
- Yeah and caves up high in the alpine
can have ice in them and you have to have
even more layers and clothes and hats
to wear when you're mapping those caves so.
- Yeah and Johanna used to work in Alaska,
I'm sure those caves were cold.
- [Johanna] They were cold!
(rangers laughing)
- Alright, this one isn't coming
from online but up here.
So you're in a cave in the desert.
Is it moist and damp like this one?
- It depends of the mean
rainfall for that area.
But for the cave to be formed
they had to have enough rain
to be formed throughout the years.
