Brian found out what animal was in the shelter with him by feeling and seeing quills in his leg from a porcupine.
Brian finds shelter in a small rock overhang near the edge of the lake. He uses the hatchet to clear some of the brush and create a makeshift shelter with a fire pit and lean-to.

Brian makes a shelter out of trees in the book "Hatchet" on pages 52-54.
In "Brian's Winter," Brian constructs a makeshift sled using tree branches and his jacket. He then ties the deer to the sled and drags it back to the shelter using branches as skis on the snow.
