Looks like this was caused by an error in the original import of the Cypress Provincial Park boundary. The original imported data included bad data from Data BC (now commonly called the BC Data Catalogue). This is a common error as BC Parks itself often has outdated boundaries, boundaries that were incorrectly transformed between coordinate systems, or just wrong data to begin with. Someone should download the fixed boundary from the BC Data Catalogue and use the replace function in JOSM to clean this up.
