The igloo is one of those snow shelters that looks really
hard to build, but, like many things that are like that, isn't really all
that hard after all.
The pictures on this page show Rob and his friend building an
igloo.
The start of the walls.
About halfway up.
This photo shows how nice the snow is for
making snow blocks. You can see that the blocks are thick and have
well-defined edges. This shows that they are holding together well.
