Hard at work in June 2003, when Christine, Josh and I spotted the expectant parent along Nihahi Creek. Both the male and female participate in the excavation. According to one source, the excavation can take up to 12 days. The hole was only about 4 feet off the ground, which surprised me. Three years later I decided to investigate the results of their efforts. Notice the beveled lower margin, which serves as a "doorstep."
