Replying to Spots on Solitude, Alta/SNowbird, and Brighton to ski

Hello Utah NS'ers, I'd like to ask where the best spots to ski on the mountains mentioned in the topic title are and why they are so great to ski. Being from the east coast and visiting Utah and the west in general for the first time id like to ski where the locals like to ski especially good pow lines. I am bringing both my sets of skis to Utah, My gotamas and thrusters but id really like to ski some good pow if possible. Thanks
