But the main cause was the huge debt incurred with the development of the integrated operation during 1905–1907. Even though the quarry had received a lot of contracts and some very lucrative, the operation (quarry, mill site and railroad) never made enough profit to pay off the start-up funding. A final disposition of the quarry was not completed until 4 April 1921 due to various groups vying for the assets. The town declined rapidly to a population of 50 people in 1920 according to the 1920 Census. The bank closed in 1918 as did the remaining newspaper. The last train left Marble in 1918. Out of bankruptcy in April 1921, the operation was on a much smaller scale than before the 1917 bust. The amount quarried was greatly reduced and experienced several fluctuations in output and changes in operators. The fortunes of the town also went up and down with the marble fluctuation as reflected by the changes in population by climbing to 600 by 1926, 550 as 1930, then dropping to 175 by 1933 with a rise to 225 from 1939 and into 1941. Though the quarry was out of bankruptcy in April 1921, quarrying did not resume until April 1922 and with divided ownership. The bankruptcy settlement resulted in the Carrara Company owning the quarry and the tram line to the mill site while Yule Marble of Colorado owned the mill site and the railroad. Both companies realized the need to cooperate and functioned as an integrated operation and later merged into Consolidated Yule Marble Company, 24 April 1924. There were other changes of owner and operators with the Vermont Marble Company, taking over as of November 1928. They in turn formed Yule Colorado Company on 14 December 1928 which continued up to the shut down at the end of 1941. Tomb of the Unknowns marble was quarried in seven pieces for four layers; cap, die, base and sub-base (plinth) from Quarry 3 at below the opening from early in 1930 to January 1931. The cap was quarried on the first try while the base required three attempts. (No data available as to quarrying the plinth). The die was worked by 75 men for one year and three attempts until a 56-ton (55.86 metric) block came out of the quarry in late January 1931. When the block was cut from the mountain it weighed 124 tons (123.69 metric). A wire saw was then brought in to cut the block down to 56 tons (55.68 metric). Because of the weight, Vermont Marble Company sent to the quarry a special derrick that was reinforced and heavily rigged.
