Guys, when you take the floatplane from Sandy, you will fly due north and fly right over a high morraine just as DD described as you make your way to Opasquia PP. it is a neat siight as most of the terrain that you will see from Sandy to Opasquia is flat with heavy jack pine forest and scattered small lakes,ponds and marsh.

When flying in the fog, it can be a bit dangerous as the high plateau comes out of nowhere and the elevation difference is quite dramatic.
