Its a good thing its difficulty protects it from becoming like c2c

Hello Cy,

Any idea where the tunnel starts on this side and where it comes out on the other?

[Cy Kaicener]

I dont know Walt, but I too would like to find out. It would be somewhere between Snowcreek and Cabazon.

Thanks Alan, but that printing is so small that I cant read it even with my glasses.

An interesting comment.

Case History: San Jacinto Tunnel, California

The San Jacinto water tunnel was completed in 1939 for The Metropolitan Water District of Southern California as part of the Colorado Aqueduct project. The 6-m-diam, 21-km-long tunnel was excavated through mostly granitic rocks with zones of metamorphic rock (mica schist, quartzite, marble) at an average depth of about 450 m. Four major faults and about 20 minor faults or fractures were encountered. There were 8 or 10 instances when peak flows of 1,000-1,100 l/s (15,000 gpm) were experienced, with estimated maximum pressures of up to 4.2 MPa (600 psi) but more commonly at 1-2.5 MPa (150-350 psi). The large surges of inflow usually occurred when tunneling through impermeable major fault zones, notably the Goetz Fault, which held back compartments of groundwater under high head. Another fault, the McInnes Fault, was approached by tunneling from both sides. Drainage into the Goetz Fault and other faults had depleted the reservoir. This resulted in an inflow less than 6 l/s (100 gpm) when the McInnes Fault was crossed. It was estimated that the tunnel job had depleted some 155,000 acre-feet of water from the aquifers; springs were affected at a distance of 5 km (3 mi).

Deep Underground Science and Engineering Laboratory (DUSEL) Proposal

The tunnel portal is near the Valley Station of the Palm Springs Aerial Tramway.

This doesn't sound good. There would be a lot of construction in Longs Valley. Not good.

Well if I'm reading all their papers correctly we are one of 3 sites being considered.

The laboratory they are talking about will go in at about 2500ft close to where one of the lowest unpaved parking lots is located. They are planning on the tunnel going through the mountain on a flat plane until it is directly under the summit of San Jacinto.

Anyone need fill rock to decorate with?

They chose South Dakota:
