New Zealand - Fox Glacier
Grab a helicopter, jump out at the top of Fox Glacier and get your spikes on.
This is a longer tunnel than my previous photo and smaller in height, hence having to crouch down to get through.
The blue is a true colour as that part of the ice has not say oxidised or been in contact with the sun for a prolonged period, its blue underneath all this packed ice of a glacier.
Note the spikes being the key to not faling over, as you can see how slippery the ice underneath is.
Nice place for shelter in adverse weather conditions or hide if you have just robbed a bank, they cannot track you through the thick ice above lol.
