I assume you heard the replica of Ft. Clatsop burned down this last year.
Yes, but it can be replaced. It was a replica anyhow and I seem to recall reading the rebuild would give archaeologists a chance to look for more artifacts and straighten out some of the errors that were made originally. All I can think of when I hear about the place is the really miserable winter the group spent there: so wet all the time their leather clothes actually rotted off their bodies. The diet was awful: boiled elk and wappato root. To this day I can't understand why Jefferson didn't send a ship to meet them with fresh supplies.
