BUNDYS ELSINORE HOT SPRING (RIVERSIDE 4).
Bundys Elsinore Hot Spring is the name of another resort, about
250 yards north of Elsinore depot. One well at this resort supplies
warm sulphureted water for drinking and bathing, and a hotel and
cottages provide rooms for about 75 guests. A partial analysis of
this water is tabulated below, with the two from the Elsinore springs:

2. Elsinore Hot Springs; original hot spring.
3. Elsinore Hot Springs; white sulphur spring.
These partial analyses show the waters to be very similar in con-
centration and properties. They are soft waters, chiefly primary
saline in character.
It is said that previous to the construction of the irrigating ditch
portions of the land near the present hot wells formed quagmires, but
most of this saturated land has since become dry. Although the
fault through this region is mapped as passing through Elsinore Lake,
2 or 3 miles southwest of the springs, the disturbed zone probably
extends to the eastern edge of the valley and includes the locality
where the heated waters now rise. The sulphureted character of the
waters is possibly derived from beds of tule mud through which they
pass before reaching the surface.
