Recently, I had the unique opportunity to tour two different oil sands operations near Fort McMurray, in northern Alberta. I saw a massive open-pit oil sands mine, and the associated reclamation effort, operated by Syncrude Canada Ltd. I also visited an in situ oil sands recovery project called Surmont, operated by ConocoPhillips (NYSE:COP).

Last month, I stood inside a shovel the size of a two-car garage.
