Hundreds of Seattle area activists were out on water and land Sunday to protest Kinder Morgan's Trans Mountain Pipeline expansion.

The protest started at Occidental Square in Seattle's Pioneer Square; protesters then marched to the Seattle waterfront.

The protest then moved to the water, where a dozen of kayaks and indigenous canoes and canoe families departed from West Seattle to surround Kinder Morgan's marine terminal.

Around 350 activists in Seattle and 350 activists in Tacoma were expected to participate.
