Two pieces of evidence, alas contradictory, that it is the Pike Lake on today's maps:
1. From Mary Lake, Hubbard's party went west to Windbound Lake. The only sizable lake west of Mary is Pike.
But this assumes that the Mary Lake on today's maps is the same Mary Lake as then.
2. Brad Bassi's map at
http://www.bassioutdoors.com/Hubbard_Ex ... outes.html shows the Hubbard party as turning back at Pike Lake.
But the same map does not show Hubbard's party as passing through today's Mary Lake.
Remainder edited from first post:
A possible resolution is that this part of Hubbard's route is marked incorrectly on Bassi's map.
The notes (I have at hand only Clayton Klein's book) refer to Mary Lake as "the lake that looked like a river", a description that certainly fits the Mary Lake at Toporama.
On the other hand, there's a stringy lake (looks like a river) to the northwest of Disappointment Lake, on line with Pike Lake. But then this line of thinking leads also to the identification of Windbound Lake as Pike Lake.
Another piece of evidence is the reference to the hill that Hubbard and George climbed and saw Michikamau.
Toporama shows a ~100 m hill at
53d 57' 51" N 62d 42' 26" W.
From there, when one looks toward the present Smallwood Reservoir, one would see the present Mary Lake as a narrow strip of water.
I think Windbound is Pike and that the two Mary Lakes (Hubbard and Toporama) are the same.
But the people whose opinions matter are Troy Gipps and Philip Schubert.
