Corrosion residues are relatively insoluable minerals which were once part of the bedrock. They were left behind and concentrated when the bedrock was dissolved. On the CCNP Cave Inventory Form, the recorder is asked only to distinguish them by color. There are three color categories on the form: red, brown and yellow. They can usually be found on the floor but could appear in cracks or vugs or on shelves and ledges. They could even appear as a type of crust or coating.
The CCNP Cave Inventory Form asks the recorder to include the thickness if possible. An estimate of how thick the accumulation is should be included next to the station.

Red CR
The Red CR field is used to record stations where red corrosion residue is found. The red is usually a rusty red color.
Brown CR
The Brown CR field is used to record stations where brown corrosion residue is found.
Yellow CR
The Yellow CR field is used to record stations where yellow corrosion residue is found. The yellow is usually a kind of dirty yellow color.
