Our revised stratigraphy for the Gaillard Cut shows that the Culebra Formation represents a transgressive-regressive, marine sequence with environments that include, from lowermost to uppermost: lagoon, fringing reef, neritic, upper bathyal and prograding delta.
Cite all applicable sources. Bathyal sediments in the upper member of the Culebra Formation suggest that a short-lived strait may have existed across the … These helped dig out the section while dynamite is poured into the high towers on the upper level of the ditch.

Time after time, as the Army Corps of Engineers was digging the Canal, the sides collapsed and filled the trench. So instead of digging ‘down,’ the engineers dug ‘up.’ They constructed a dam and filled what is now Gatun Lake.

Explain in detail. By January 1912, when this picture was taken, much of the Cut had been excavated and a crew of 150 men are seen here shifting tracks by hand for the steam shovels to complete their work.Create an email alert based on the current articleIn May 1913, crews of hundreds and several steam shovels completed the digout of the Culebra Cut – which measured around 12km in length. The building of the Culebra Cut, later renamed Gaillard Cut, took place from 1907 to 1913. Starting with door to door sales and eventually branching out into freelance photography work, the brothers' company grew large enough to relocate to New York City in 1891.
