when they dumped the rock into the bay mud, it was like dumping rock into jello. it went down into the mud so that they could build off of that. it then took the angle of repose. it is stable. san francisco came and built piers on piles over the top into the water. >> the piers are built up over the water. >> refusal is when you cannot advance the pile anymore. this is under the bay mud over there. they meet refusal. they gain support and bearing on top. saltwater attacks concrete. in the old days, they did not understand the effects of salt water, chloride on concrete and steel. a lot of these piles may have started out 24 inches in diameter. they may only be eight or 10 inches in diameter now. whatever steel was in there is long gone all along the waterfront. >> wonderful buildings. at the double dog and a beer. >> this is wonderful. it is right on the waterfront. it is due piles. >> that is the location of what is now the san francisco port authority? >> yeah, port offices. and there is a new office there and slip. this is one of the few places where they recent

rock week. 100 years later, the weak rock cannot stand there anymore and it fell. this slide is a long sansome street, where the city chose to protect sansome street and the cars, and they built this catchment wall. the sole purpose of this wall is to catch rocked that falls from private property. >> and every year or two, we get a call saying that rocks have fallen down the road and spilled over. this is the famous slide where we had a building at the top fall down this hill. this is the 22 street building. this was a watercolor done in 1945 by david mandel which -- by david mandelowiz. this building started gradually falling and sliding down. >> they had to replace the street right there. and in the process of jack hammering out the old st., they weakened the rocked. then the rockfall occurred. it undermined the building. once the building was undermined, it could no longer state occupied, and the decision was made to remove the building. as you recall, it made headlines. eventually, the building was removed and a new wall was built. the lot where 22 once sat is s

that is the rock site. they dug down, put it on rock. as you move north, you come to the southern pacific building or the embarcadero centers or the trans america towers. there, the rock is 40, 60 feet deep. but the decision was made that we need parking. so they elected to dig down to the dents supporting soil and build a foundation on the dance material below the bay mud. so that is a rock site, rock expedite -- rock excavation. this is part of the temporary shoring system that retains the walls of the excavation and prevents the building, other buildings from falling into the hole. >> where were we? >> we were driving around in the marina. we were looking over the perfectly flat marina green, at the whole marine area, which is also perfectly flat because it was artificial filled from the 1915 exposition. >> that is correct. it was hydraulics and pumped in from the bay. same principle, they built a dike on the outside it, and then pumped in the sand. and as we all know, in 1989, a lot of damage. lawrence can speak to the concept of soft

the rock under here is franciscan. it is sandstone. it is probably the hardest rock in san francisco at this location. we have just recently completed an investigation for the expansion of cathedral school, and they chose to go down 20 feet below the surface of the street, and it was incredibly hard. it was harder than the concrete that was placed as a foundation. the rock beneath the concrete was 10 times stronger than the concrete that is used to support the building. >> okay, moving to another part of the city, this is the eastern side. >> this is on army street? >> yes, this is army st., se. look at all that stuff. it is an active city. >> a lot of the old industrial, the american can co., goodman lumber. all that good stuff. >> wow. >> and this building is one of the examples of remaining 1906 earthquake damage. it has been repaired above, and that is where they repaired the damage. what did they found these buildings on, back in the early days? >> those days, remember i mentioned early on, it would use of redwood grillage and they

because of this blasting that occurred, the rock is weak. while most of the time, there are times of heavy rain. sometimes, this has nothing to do with the rainfall. iraq is 50 to an old and then it just falls. in this particular area where we're standing, we have seen the wall at the base. >> the big steel beams with the fence. this is an effective way of preventing the rock that does fall from causing damage. that might protect the bottom of the hill but it doesn't do anything over the hill. >> it has long been my understanding that the city of san francisco says and the building department takes this position that there is no one buildable lot -- unbuildable lot. i wonder if this is realistic. >> if money is an issue, we can develop solutions that will mitigate the impact. that a solution can be eliminating the hill, that can eliminate the problem. or build a structure right into the hill so there is no longer an exposed face or bold enough of iraq together so that it acts as a big buttress to prevent further movement. -- or hold enough of

part of the fantasy of the rock and roll fantasy camp is, you don't know what you're going to do when >> reporter: i need to tune. >> if you know the words, you might be a singer. >> reporter: be y default? mark decides i'm going to take lead on "the wait." which immediately sounds like a horrible idea. ♪ you put the load right on me >> we let the song become our song that we take with us for the rest of our life. >> reporter: luckily, i get to take a backseat on "pure poison." it's a catchy little rocker written by sara from dallas. >> let's go from the top now. >> reporter: and polished by our producer. >> and do a little -- ♪ >> reporter: magically, these nine strangers get tighter with every note. so much that it inspires tommy lee to jump in for a little jam. ♪ ♪ >> reporter: and as long as he's around, might as well soak up some knowledge. >> i think part of the package is, i get to trash my hotel room. do you have any tips for me? >> yeah, we're going to need a lot of extension cords. people -- what they do, they make the mistake of throwing the tv set out the window. if you do

the year. >> nationalize northern rock. they put a for sale sign up. they hope to raise about 1 billion pounds. this is not a great deal for taxpayers. >> i can announce tonight that on behalf of you, the british taxpayer, i have decided to put northern rock up for sale. images of the lines outside of northern iraq branches or a symbol of all that went wrong. -- northern rock branches are a symbol of all that went wrong. >> they would like the chancellor to impose taxes on financial trading which they see as a casino. the chancellor has a different answer. for the huge banks like will bank of scotland, hsbc, they would like a bear investment activity to be insulated. in a crisis or collapse, these retail operations are less likely to be damaged. >> this will not stop another financial crisis. it will not stop having to bail out a banking system. the idea that you can walk away from an investment bank and let it collapse, look at lehman brothers and see what happened. this a virtually brought the world banking systems to their knees. >> economic kopit's

it's one of the most powerful images in rock. springsteen leaning on clemons' shoulder. they were literally joined at the hip before day one, before springsteen was famous, clemons was in his band and you know, he was as much a part of that stage presentation as springsteen was in many ways. >> you know, people have written about it and they have -- he's talked about it as well, clarence clemons and bruce springsteen about the night they met in asbury park in new jersey. they said it seemed like destiny that they sort of fulfilled each other's destiny when they met in the late '60s, early '70s. >> well, it's a crucial part of the springsteen story. there's a lot of the myth attached to it, you know, the big storm, the door blows off the hinges. there's this is 6'4", 250 pound guy standing in the doorway and walks up on stage and springsteen is saying whatever you want, man. come and join my band. and they hit it off musically. they hit it off with karma. they hit it off as friends. it was a true friendship beyond being a musical relationship. and it can't be stated enough

[laughter] and then huntsman perfectly described true americans. >> people secure in their rights and in love with their liberty. >> stephen: yes, i'm passionately in love with my liberty! i'd say i lust for it.

clearly, you saw the potential of rock and roll and hip-hop married together. ou saw a new kind of comedy, and now you're on the cutting edge of poetry as well. what do you see in the next five to ten years? who will be the cultural leaders? and what's what's coming for art, rock and roll, and music? well, let me say this to you. if someone picks up a sitar tomorrow and plays the [...]-- i mean, really does his thing with that sitar, then everybody's gonna run off and play a sitar, and they're gonna say, "what a great phenomena that is. sitar is the hottest new instrument." but that someone-- you know, i'm not in touch with all of the millions of creative people there are, and the trends begin not-- you know, things that are right immediately in front of us and you see them happening-- i might have heard a sitar, and now my bands are playing with sitars, but that thing, the foresight of-- of what cultural phenomenas will come on us is one i leave for those people who are calculated and are not creative, 'cause creative people know that the heart creates, you kno
