Neat website about that big rock, Kreigh!


Some erratics are big. You might enjoy the size of the biggest one?

and the interesting legend of how it split in two.?

And, alas, I'm afraid your post was a great disillusionment to me, because I couple of years ago I had visited, and was very impressed by, the Madison, Carroll County, New Hampshire, glacial erratic, a N.H. State "Wayside Monument" and locally known as "the largest known glacial erratic".? It is,


"Madison Boulder is a huge granite rock measuring 83 feet (25 m) in length, 23 feet (7.0 m) in height above the ground, and 37 feet (11 m) in width. It weighs upwards of 5,000 tons."

Your Okotoks Erratic "Big Rock" in Alberta has?clearly got it all beat,

"The Okotoks Erratic weighs 16,500 tons. It measures 9 metres high, 41 metres long and 18 metres wide."

and?evidently holds the world record, as is stated in the very good Wikipedia article about glacial erratics,

Next time I'm in Alberta (never been there, actually), I've got to see it!

Cheers, Pete
