Vernal pool monday

Tamposi Land, Vernal pool #1, Rain showers

Another wet day in the field but many accomplishments. The mapping of the perimeter of the pool is complete and I am surprised at how big it is. With this data, we'll do some mapping using acr view and I plan to make a map by hand. It is an exercise I do with my 7th graders as an introduction into compass, map, gps and orienteering. With the directions (bearings) and distances, it is quite easy to make a pretty accurate map of anything. A set of parallel rulers and a protractor are a must. A couple more days of field work and a little exploration in the land west of the vernal pool.
