Sequoia Kings Canyon National Park (SEKI) has published its 2016 guidelines. Containers are required in the Dusy Basin, Rae Lakes Loop, North Dome and Rock Creek areas from May 1 through October 31. Ursack is allowed in all other areas of SEKI. The list of SEKI approved food storage containers does not include or mention Ursack. There has been no explanation given to us despite the fact that SEKI has had years to evaluate the IGBC approved Ursack S29 AllWhite. Our letters and phone calls have gone unanswered. Ursack’s perfect record has been ignored. We are not aware of any bear anywhere in the world, much less SEKI, that has torn a greater than 1/4 inch hole (the IGBC standard) in an Ursack S29/S29.3 AllWhite.
