About 150 men who had been spending their days stringing a power line from Saticoy to Saugus were sleeping in a meadow inside canvas tents with wooden floorboards.
Indeed, the site had been inspected twice, at different times, by two of the leading geologists and civil engineers of the day, of and ; neither found fault with the San Francisquito rock. Wear sturdy lug sole shoes and protective clothing. Francis Dam during construction looking upstream. Schematic showing the downstream distribution of concrete dam fragments and their suspected original placement at the dam. As with others, Mulholland inspected it, judged it to be another contraction crack and ordered it filled with and grouted to seal off any seepage.

Just this lil 'k-turn' the directions mentioned. The implicit mechanism was that the weak sandstone on the west abutment quickly gave way as soon as it was exposed to water and that the dam collapses from west to east by some unspecified mechanism.

Nonetheless power to most of the areas not flooded was restored with power from Edison's Long Beach steam electric generating plant.
