Thirty yards below the main spring a similar spring has formed a
small natural basin, and at about the same distance upstream car-
bonated water seeps from the bank and has heavily iron stained it.
Other seepages that issue along the creek bed have stained it with
iron for a distance of nearly a quarter of a mile above the main spring.
Soft shale that is overlain by gravel is exposed along the creek.
At a few places several hundred yards eastward, upstream from the
springs, inflammable gas is said to rise, making its presence known
by bubbles when the ground is wet.
The property has been open as a resort since 1902 or 1903. In
1909 tent houses and a dining room provided accommodations for
about 50 people.
CARBONATED SPRINGS NEAR FELIZ CREEK (MENDOCINO 28).
About 3 miles west of Hopland, in a ravine on the slopes above
Feliz Creek, are two small springs. One of these springs is notice-
ably carbonated and deposits a little iron along its channel, whereas the
other is less distinctly carbonated but tastes noticeably of hydrogen
sulphide. The two springs are about 20 yards apart, on opposite sides
of the ravine, and issue from banks of crushed sandstone and siliceous
shale, near the side of a wagon road. In 1909 the carbonated spring
formed a box-curbed drinking pool. A brick-lined basin 3 by 6 feet
had been constructed at the sulphureted spring, and a pipe led from
it to the roadside.
