At the beginning of 2018, Terra Lumber Company purchased a timber tract from Boise Cantor for $4,230,000. After the timber is cleared, the land will have a residual value of $690,000. Roads to enable logging operations were constructed and completed on March 30, 2018. The cost of the roads, which have no residual value and no alternative use after the tract is cleared, was $354,000. During 2018, Terra logged 590,000 of the estimated 5.9 million board feet of timber. Calculate the 2018 depletion of the timber tract and depreciation of the logging roads assuming the units-of-production method is used for both assets. (Do not round intermediate calculations.)
