This is one of the finest Post Offices you will ever visit. It is also one of the smallest Post Offices you will ever visit. Michelle W. is Postmaster. She is great--absolutely superb! She knows Post business like no other Postmaster. She learned the trade from Gloria C. who retired in September 2006. The whole community of Clayton rallied 'round Michelle and wrote letters and circulated petitions, etc. in order to get Michelle appointed as Postmaster. For once, the right thing actually happened and Michelle got the position. This is a truly lovely little Post Office and, if you're driving along the Salmon River, please stop in and say HI! Stamp collectors often frequent the Clayton Post Office because it has such a great selection of hard to find issues. The Post Office was founded October 19, 1880, back in the days when Clayton had a little smelter sitting alongside the Salmon River. read more
