It is always interesting to note changes in the flora since the advent of man. With this end in view, the writer made some notes on the plants found in the Clear Creek Canon, Colorado. The first settlement was made in the vicinity of Idaho Springs. A small monument marks the discovery of gold in this region in 1859, on what is known as Chicago Creek. Gold mining has been carried on in this vicinity continuously since.
