Geocache Description:


San Sevaine Cultural Well

CACHE NOT AT THE POSTED COORDINATES LISTED


There are as many as 2 million water wells in California, with approximately 10,000 to 15,000 new wells constructed each year. They range from hand-dug, shallow wells to carefully designed large-production wells drilled to great depths. More wells are being drilled now than ever to capture water in the last decades due to the limitations of available surface water. There are several types of water wells. Drilled wells are constructed by either cable (percussion) or rotary-drilling machines.


Drilled wells that penetrate unconsolidated material require installation of casing and a screen to prevent inflow of sediment and collapse. They can be drilled more than 1,000 feet deep. The space around the casing must be sealed, 50' deep for domestic use, with grouting material of either neat cement or bentonite clay to prevent contamination by water draining from the surface downward around the outside of the casing.

Driven wells are constructed by driving a small-diameter pipe into shallow water-bearing sand or gravel. Usually a screened well point is attached to the bottom of the casing before driving. These wells are relatively simple and economical to construct, but they can tap only shallow water and are easily contaminated from nearby surface sources because they are not sealed with grouting material. Hand-driven wells usually are only around 30 feet deep; machine-driven wells can be 50 feet deep or more.

Dug wells, historically, were excavated by hand shovel to below the water table until incoming water exceeded the digger’s bailing rate. The well was lined with stones, bricks, tile, or other material to prevent collapse, and was covered with a cap of wood, stone, or concrete tile. Because of the type of construction, bored wells can go deeper beneath the water table than can hand-dug wells. Dug and bored wells have a large diameter and expose a large area to the aquifer. These wells are able to obtain water from less-permeable materials such as very fine sand, silt, or clay. Disadvantages of this type of well are that they are shallow and lack continuous casing and grouting, making them subject to contamination from nearby surface sources, and they go dry during periods of drought if the water table drops below the well bottom.

Cultural wells are a category of themselves. Most of these wells are naturally formed. In parched climates, like in the deserts of California, most of these wells date back hundreds of years and some still function. You may have heard of Indian wells which are considered natural wells, San Sevaine is a cultural well as well, no pun intended. This well is monitored regularly as part of the State's and local region agency that manage water availability. A locked iron lid is placed to protect the integrity of the well.You will find a path to the well and nearby the cache as well. Getting here will be a challenge. You may find the gates locked along Big Tree Cucamonga Truck Trail / Old CC Spur during the year. Terrain would be a bit more difficult trekking in. The cache is placed in a typical location for this environment. Be safe!
