Hello! I’m looking for a book I read as a child in the 80s (could be older as I purchased thrift store books a lot). It’s about 2 siblings, boy & girl, who have a dad that takes people out in the wilderness as a job (hunting, fishing, camping maybe). The 3 of them go on a wilderness camping trip, & drive quite a ways to get there. Some sort of accident happens (car wreck? Can’t remember), & the father passes away. The 2 kids have to journey to safety on their own, using tactics their dad had taught them.
