In addition to below I found basalt was used in paving blocks which I believe was used in the tunnelcin 1930's. Not much to add but following excerpts...<br /><br />Query[history basalt california]<br />http://quarriesandbeyond.org/states/ca/stone_industry/ca-stone_indust_upto1950_2.html<br />"By 1913 approximately 74 quarries were in operation in the San Francisco Bay area. Of these, 43 percent produced paving blocks; 30 percent, building blocks; 25 percent, crushed stone used for concrete and road metal; and 2 percent, abrasives including ground pumicite."<br />"(Circa 1950)California has the largest commercial output of rock products of any of the 48 states. It is far ahead of any other state in production of sand and gravel, and ranks near the top in production of crushed and broken stone. Of the total rock products produced in the state about one-third comes from the San Francisco Bay counties"<br />Rosemary Mhttps://www.blogger.com/profile/12291661159622665464noreply@blogger.comtag:blogger.com,1999:blog-4953008377950396317.post-82360914794375009992013-03-25T23:17:46.979-07:002013-03-25T23:17:46.979-07:00Under the adagio “if you don’t know the answer, tr...Under the adagio “if you don’t know the answer, try to find someone else who knows” I contacted the several times mentioned Dr. Stephen W.

However, the contractor, the Six-Man Company, was unable to complete the construction stages in a timely manner. With 68 percent of the project complete, the contract was broken down into smaller contracts and awarded to individual companies to complete the project.”<br />Rosemary Mhttps://www.blogger.com/profile/12291661159622665464noreply@blogger.comtag:blogger.com,1999:blog-4953008377950396317.post-32053426114282145452013-03-24T06:25:34.616-07:002013-03-24T06:25:34.616-07:00Here’s a recap of the Caldecott Tunnel Constructio...Here’s a recap of the Caldecott Tunnel Construction<br />https://docs.google.com/file/d/0B1sx0iUA-aNRbGl2NlVuOEdPa28/edit?usp=sharing<br /><br />And here’s an article that connects Kaiser to the Caldecott Tunnel contract.<br /> <br />http://www.sfgate.com/bayarea/article/TUNNEL-VISION-The-traffic-jams-started-the-day-2791228.php<br /><br />“As we all know, the Broadway site won out, and in 1934 $2.8 million in bonds were sold, $1 million in federal money was secured and a $3.7 million bid by Six Companies of California, the consortium that built Hoover Dam, was selected by Joint Highway District 13, the local agency formed to build the tunnel.”<br /><br />Note in the above the mention of the Six Companies Group(which I know from earlier research was actually 8 companies) and Henry Kaiser was the lead negotiator for this group. From the research we may be assuming Kaiser Sand and Gravel owned the quarry in question, but I think it’s possible that it was one of the other 7 companies in this group of companies. It may have just been recorded in history inaccurately.<br />That’s all I found and perhaps it will help complete the search.<br />Rosemary Mhttps://www.blogger.com/profile/12291661159622665464noreply@blogger.comtag:blogger.com,1999:blog-4953008377950396317.post-85415885149803585792013-03-23T17:59:10.259-07:002013-03-23T17:59:10.259-07:00checked out the link provided by maca that referen...checked out the link provided by maca that references <b>a</b> Kaiser quarry and an RCM operation of the former Harrison-Birdwell quarry that are "near" each other and the "Tunnel Rock quarry located near the east end of the Broadway tunnel."This site actually appears to be in SF, south of Russian Hill - the location of the Broadway Tunnel. <br />Looking at these 3 locations seemed to indicate they were all out of the area (Sibley) in question.

View north. The two peaks in the distance are Grizzly Peak (l) and Vollmer Peak (r). The foreground has equipment pads related to the Kaiser lava-rock quarry that was here for about 75 years. The basalt beds hold up the ridge on the right and are extensively quarried, revealing deep cross sections of a small volcano that existed here about 10 million years ago. Since that time the volcano and the sedimentary rocks beneath it have been folded and tilted eastward. You can see the layering of the sedimentary rocks in the nearmost ridge. Conglomerate rock has less soil and dries out brown, while the shales retain water better and support thicker growth. You can see the rocks are now tilted almost vertically. State route 24 runs behind the ridge in the middle distance, entering the Caldecott Tunnel under the ridge just off to the left.<br /><br />Photo taken in 2005; quarry that was here for about 75 years => quarry opened in the 1930s (but no "scientific" proof).<br /><br />Unfortunately no lat/long coordinates from the EXIF data.<br />Hanshttps://www.blogger.com/profile/16362447090339269962noreply@blogger.comtag:blogger.com,1999:blog-4953008377950396317.post-67404643760377551222013-03-23T07:26:07.715-07:002013-03-23T07:26:07.715-07:00Okay totally off topic but actually is interesting...Okay totally off topic but actually is interesting.

And there are even a fair number of pages with "Round top" and Sibley in them, as that's the name of a mountain ("Round Top") in the Sibley park. But if I require that the word "quarry" be on the page, then that will give me ONLY pages that have the word "quarry" on them. In other words, it really reduces the number of false positives (that is, pages that look good, but don't actually have anything on them about quarries). <br /><br />I also experimented with [ "round top" intext:quarry OR intext:mine OR intext:mining sibley ] -- but it turned out to be overkill.

It would seem reasonable from a liability standpoint that private enterprise mining operations wouldn't be occurring in areas open to the general public. <br />It would also seem likely that a large percentage of the product produced out of the two quarries was used in the Caldecott Tunnel project - indeed, as you discovered, one of the quarries was named "Tunnel Rock Mine". The Caldecott project started the first two bores in <b>1929</b> and completed that phase in <b>1937</b> and that time frame would/could roughly correspond with the quarries in question being in operation.
