Olympic Habitat Development Study
Two salamanders with luggage walking in forest toward a very large pyramid made with logs.  Caption says DUUUUDE!  SOMEBODY GOT LITERAL ABOUT THOSE LOG PYRAMIDS!

Log pyramids were designed to create larger log structures from smaller logs (but to limit the use of very small logs so the pyramids would last longer). The intent was to create long log structures (as would exist naturally) and not to recreate Egyptian burial structures in the woods! You might have a better term for the log structures than pyramids. We used the term to imply the structures were built in a orderly fashion and the logs were arranged purposefully and not put into a large irregular pile.
