摘要： A log staircase is disclosed along with a method of producing components for the log staircase. The log staircase includes an elongated stringer capable of angularly extending from a lower level to an upper level. The stringer has an outer circumference with a notch formed therein. A protuberance extends upward from the notch. The log staircase also includes a tread having a semicircular periphery with a flat surface. An opening is formed in the semicircular periphery of the tread. The opening is designed to mate with the protuberance to retain the flat surface crossways to the stringer. The method includes cutting a number notches and protuberances in each of a pair of stringers, and cutting a pair of openings in a predetermined number of treads which are capable of mating with the protuberances to retain each of the treads crossways to the pair of stringers.
