I have a 6061 Heat treated GT Tempest frame, which currently my favourite bike, 16" frame with 6061 stamped on the rear drop out, but it's not an Avalanche frame as it doesn't have an integrated seat clamp or externally butted head tube. Nonetheless it's a nice frame! I'll have to spend some time polishing up properly when the weather improves!Yeh from 98 they started to use 6061 on avalanche. They were getting ready to move production away from USA for the high end stuff so started to experiment.
Interestingly a I had a painted 6061 Avalanche which was lighter by a few grams than a Painted same year Zaskar.
