You can check the K2BSA 2013 Jamboree Logbook here
Note that this logbook only contains QSOs from the 2013 Jamboree Operation. It does not show QSOs from many other K2BSA operations where the call sign has been reserved for Scouting events throughout the USA. You can find a list of those operations on the page titled QSL Paths.
Via Club Log we've provided a method for requesting direct QSL cards for non-USA stations. This service is exclusively for the K2BSA National Scout Jamboree Operation from July 15 to July 24, with a few earlier setup QSOs. It is also primarily for non-USA contacts and their direct QSL requests. Requests are $2 USD for direct cards. Bureau cards are automatically sent right after the Jamboree.
If you are a USA contact, please send your QSL along with an SASE to Jim Wilson, K5ND, 2605 Valleywood Drive, Grapevine, TX 76051.
