Figure 16. Outflow chemistry from two snowmelt seasons (1986 and 1987) at Emerald Lake, a high-elevation lake in the Sierra Nevada Mountains of California. Maximum N03 concentrations are coincident with ANC minima during the early stages of snowmelt in 1986 and with a rain-on-snow event in 1987. Nitrate episodes are smaller in magnitude than at sites in the eastern United States, hut western lakes may he more susceptible to episodic acidification because they have a lower baseline acid-neutralizing capacity than most eastern lakes.

Native sulfur. Elemental sulfur is deposited at the edges of some hot springs and geysers. This formation surrounds Emerald Lake in Semite National Park. 

Within a given granitic rock suite, the halogen concentrations in apatites commonly vary as a function of whole rock Si02. For example, in a study of the gold-mineralized Emerald Lake pluton. Tombstone Suite, Canada, Coulson et al. (2001) attempted to use fluid composition determined using apatite and biotite chemistry to infer the source of... 

At last, you glimpse shining water through the trees ahead, and come to the shores of a great lake, set like a shining crystal in the emerald heart of the forest. In the center of the lake is a small island. You are wondering how to cross to it when a gentle voice speaks ...
