Three-Dimensional Impressions<br />
Three-dimensional impressions are those that have a significant depth, in<br />
addition to the length and width of the impression. Commonly, they may be found<br />
in soil, sand, or snow and the detail within the impression may vary according to<br />
the substrate. Casting is an effective method of collecting these types of<br />
impressions. Impressions should always be photographed prior to casting.<br />
Photographs, however, are not considered substitute for a cast. If a lengthy tire<br />
track is encountered, an attempt should be made to cast a section at least three<br />
feet in length.<br />
