Does anyone from the northeast have thoughts on Clyde Kennedy’s suggestion for concrete, 6×6, and 2×8 step construction? Will that design really withstand serious winters? I am in the snow belt in Rochester, NY, and I am skeptical but interested. I am wondering if a layer of concrete is needed under the 6x6s or not. His design suggests not. Thoughts?

Nothing wrong with screwing down a 2X8 to a 6X6, but I don't like the way the 6X6 is fastened in place. In my mind I keep seeing water seeping in the joint between 6X6 and concrete and I see the lag bolt threads loosening up over time and I see the 6X6 getting wobbly.
IMHO, all the 6x6 wood work is doing is trying to dress up a set of concrete steps. I would rather have large concrete patio style steps as depicted in the picture, and forget about the wood "window dressing."
I understand why the 6X6 is laid on compacted gravel, to help wick away water. If the 6X was lying on top of the concrete pad (notice how the 6X is "keyed" in place by the lower conc. pad to help hold it in place) water would simply sit in the keyway area, and in winter freeze and eventually crack the concrete.
If I wanted Timber steps, I'd frame each step with 6X6s (sides, front and rear), stake them in the ground on top of one another, and then fill in the cavity with crushed limestone roadbase. If I wanted concrete steps, I'd form and pour concrete steps. But that's just me. Everyone has different tastes.
