I have only been in Prince William Sound just once. I am lucky enough to have a relative that has a motor yacht parked in Whittier.  From what I hear it is unbelievable and the more you spend in the sound the more you like it.  The pictures are from my only time so far in the sound and I think they prove it.

The two places we went in the sound were Long Bay and Blackstone Bay. The glacier pictures were taken in Blackstone Bay and i pretty sure the name of the glacier is Blackstone. 

The pictures of the boat and the river were taken in Long Bay.  The waterfall is at the end of Long Bay. The tide on this day was around 17 feet.  It was only during high tide that we could get the inflatable close to the waterfall. During low tide the water behind the picture with the inflatable would be gone and only a stream would be left.

One of these days I hope to get the video I took online.
