Fig. 4. The north-south (onshore-offshore) variation in sand content in northern Long Island Sound. Track locations are shown in Fig. 3 north is to the right of this graph. The solid line is the predicted steady-state sand content with 1/ = 0, it = 70 cm /sec, g = 3.0 X IO" /sec.

Fig. 3. (a) General locations of hydrothemial power plants in the continental United States (6). Power is produced directiy from hydrothermal steam indicated by the steam plume at The Geysers in northern California. At all other locations, hot water resources are utilized for power production. In 1993, a hydrothermal power plant also came on line on the island of Hawaii, (b) Location of The Geysers steam-dominated hydrothermal field (D) in Lake and Sonoma counties, within the boundaries of the Cleadake—Geysers thermal anomaly (B).
