Geologists use all kinds of tools on field expeditions, ranging from huge trucks to tiny hand lenses. Some tools, such as maps and rock hammers, are used on all field expeditions. Other expeditions, like those to collect large boulders for the Gottesman Hall of Planet Earth, require special equipment like dynamite and front-end loaders. The most indispensable tools, however, are hands and feet. Museum geologists have scrambled up a lot of steep slopes, pried a lot of rocks out of outcrops, and hefted a lot of boulders to assemble the Museum collection.
