grays and. rich, browns. On the side next the creek the running 
water has iaai.e a net-work of streams. In these where the water 
is still hot, the colors are bright, varying from a creamy white 
to the brightest yellows, but, as the water becomes cooler, farther 
down, the colors grow darker and richer, the siennas greatly pre- 
dominating, while the basins of the larger pools are stained with 
still darker colors, frequently of a purple tint and reflecting 
the picturesque groups of pines on their dark surfaces. Scattered 
irregularly over the whole surface are numberless little areas of 
dry deposit, from which the brighter tints have faded but which 
still retain such a great variety of purple and blue grays that the 
harmony of the whole field of color is delightful."
