During their stay at Fort Clatsop, the Corps became very homesick. It rained continuously, and that didn't help. There were only 12 days that winter without precipitation. This caused the insects to be worse than in a cold, snowy winter. Gass wrote: "The year commenced with a wet day; but the weather still continues warm; and the ticks, flies and other insects are in abundance, which appears to us very
extraordinary at this season of the year, in a latitude so far north."
