EL PAJARO SPRINGS (SANTA CRUZ 3).
El Pajaro Springs are situated near the northern bank of Pajaro
River and about a quarter of a mile eastward upstream from the
Southern Pacific Railroad bridge near Chittenden station. At least
12 cool, strongly sulphureted springs issue at this place along a
sloping bank about 20 feet high that borders a flat willow-grown
area along the river. The springs rise at intervals of a few yards for a
distance of about 120 yards along the bank, being 25 to 50 yards from
the edge of the river during normal stages of the water. Three of
the springs, each of which yields 1 or 2 gallons a minute, have been
used locally for many years for drinking. One of these has been
known as the Railroad Spring, as it has been a favorite with some of
the railroad men. The other two, which are about 75 yards north-
west of it, are known as White Sulphur Springs. The water of the
Railroad Spring has the dark appearance that is characteristic of
so-called black sulphur springs, but it becomes milky from suspended
sulphur when it stands in an open vessel for a short time. The water
of the White Sulphur Springs becomes milky and deposits native
sulphur after flowing a few yards from the sources. The difference
between the Black Sulphur or Railroad Spring and the White Sul-
phur Springs is possibly due to different degrees of oxidation of the
sulphide constituents in the water as it reaches the surface. The
same feature is shown in several minor springs of the group.
