Faldage, if you can't feel the force of the "sh" in push, then your imagination is turned off.
This is a matter of dynamics and delivery:
"Sh's" a lot of things--a lot of forces--"sh" at pianissimo is just right for that babe in arms--but, give it a fortissimo--and you've got the force of football--push 'em back, push 'em back, way back!--and at 10,000 times fortissimo, you've got your glacier pushing, too. Glaysher, that is.
However, all that said, I liked a great deal what you wrote about that canoe, though it's no glacier.
Best regards,
