We go out every scheduled day, irrespective of the weather. Wear a hat and be careful to apply sunscreen for skin protection at the high elevations. And bring and drink a lot of water. The conditions can be unexpectedly dehydrating. Supplies You should bring a map board for traditional work in the field.
Many students construct a map board out of plexiglas with duct-tape hinges.
This allows you to view your map while it is protected from rain, dust, and rocks. A couple of inner-tube strips are a handy way to hold the map down on the map board. A hand lens, hammer, and pocket knife will be useful. You will need three waterproof field books - paperback variety is fine. We collect and grade the field books with the projects, so you need a second and sometimes a third one depending on the grading schedule.
