Sheridan Logging and Lumber Company owns 3,020 acres of timberland on the north side of Mount Leno, which was purchased in 2008 at a cost of $500 per acre. In 2020, Sheridan began selectively logging this timber tract. In May 2020, Mount Leno erupted, burying the timberland of Sheridan under a foot of ash. All of the timber on the Sheridan tract was downed. In addition, the logging roads, built at a cost of $144,100, were destroyed, as well as the logging equipment, with a net book value of $277,600. At the time of the eruption, Sheridan had logged 20% of the estimated 509,950 board feet of timber. Prior to the eruption, Sheridan estimated the land to have a value of $210 per acre after the timber was harvested. Sheridan includes the logging roads in the depletion base Sheridan estimates it will take 3 years to salvage the downed timber at a cost of $676,400. The timber can be sold for pulp wood at an estimated price of $3 per board foot. The value of the land is unknown, but must be considered nominal due to future uncertainties Determine the depletion cost per board foot for the timber harvested prior to the eruption of Mount Leno.
