The Calgary Fire Department has given the all clear from the scene of two explosions Tuesday afternoon.
It turned out to be two transformers on a power pole, near the Ranchmen's that blew up.
Kevin Parker witnessed the blast. He says it sounded like a more major explosion than just a transformer.  He says the smoke billowed up and out like a mushroom cloud for about five minutes before the fire department showed up.  The explosion ignited a small grass fire which fire crews were able to quickly contain.
No one was hurt
