The Age Appropriate Guidelines for Camping in the Guide to Safe Scouting (Jan 2019) defines National and Council High Adventure as being appropriate for ages 14, or 13 AND completed 8th grade.
But Sea Base and several other camps set eligibility at 13 with no 8th grade requirement. The timing varies. Sea Base is 13 by the adventure start, some are 13 by other dates throughout the year.
BSA website for Scouts BSA Outdoor Program (https://www.scouting.org/outdoor-programs/camping/scouts-bsa-outdoor-program/) says 13 by Jan 1st of the year they participate for council and that age requirements for National High Adventure Bases vary.
Which is right? G2SS, or the camps and BSA site? (Philmont and Northern Tier have age requirements like G2SS) In the event of an issue, would the lower age limits be covered by insurance?
