The cemetery is on a 30 foot high bluff overlooking the bay.

Chinook salmon returning in surprising numbers to Cowichan River
In 2009, the numbers dropped down to just 500 pairs of Chinook returning. Yet, as of Tuesday, more than 8,000 Chinook had returned to their Cowichan River spawning grounds. The improvement is the result of years of conservation efforts by Cowichan Tribes, who have worked to restore the river to its course before logging operations changed the river.

Whitehorse fish ladder sees fewest chinook salmon since 1977
The number of chinook salmon that reached the Whitehorse fish ladder this year hit a 40-year low, and it's not clear why. Just 282 chinook passed through the fish ladder this year, compared to 690 last year. "We did see some large pre-spawn mortality die-offs in a tributary of the Yukon River — the Koyukuk in Alaska. This was for summer chum, and not chinook — but we expect that that higher water temperature also affected the chinook migrating through."

Canada's dry lakes and dust storms 'warning for planet'
For 300 years, glacial runoff was the major water source for Kluane Lake, flowing in by way of the Slims River. But in May 2016, Kluane Lake levels dropped precipitously. The problem was a case of "river piracy" — incredibly rare, and hugely significant. The terminus or end of the Kaskawulsh glacier had receded enough that a glacial lake that fed the Slims River suddenly drained when the glacier outflow found a new direction to a new river.
