Good Morning #Canada
Just a few years after we were married my wife and I rented the upper half of a duplex near High Park. The East-West road we lived on was considerably higher than the one south of us and we could see Lake Ontario through gaps in the houses across the street. I learned this week that a few years ago I could have had beachfront access out my front door.
Glacial Lake Iroquois was a prehistoric proglacial lake that existed at the end of the last ice age approximately 13,000 years ago. It was essentially an enlargement of the present Lake Ontario that formed because the St. Lawrence River downstream from the lake was blocked by the ice sheet near the present Thousand Islands. The level of the lake was approximately 30 m above the present level of Lake Ontario. Being born 13,000 years too late probably saved me from paying a lakefront premium on my rent.

Ancient seafloor lava rubble stores vast amounts of carbon dioxide, researchers discover
Sixty-million-year-old rock samples from deep under the ocean have revealed how huge amounts of carbon dioxide are stored for millennia in piles of lava rubble that accumulate on the seafloor.

Of interest to experimental petrologists, upcoming virtual workshop "to discuss and plan to address systematic bias in predictive models caused by the way trace element partitioning data is currently published." #geology #geochemistry ⚒️

Overview
This workshop overview page outlines a February–March 2026 virtual event for experimental petrologists, editors, and program managers to address systemic bias in trace element partitioning data by advocating for publication of raw analytical data to support FAIR principles, improve model accuracy, and establish community-driven data standards.

Death Gulch at Yellowstone is "a natural death trap for animals" due to CO2 and H2S accumulation. "At high concentrations..., these gases are lethal, and the death of one animal is thought to lure in others, who are then also overcome." Also, description of Wahb Springs.

Good Morning #Canada
I was in My local hardware store yesterday and saw that they had pallets of salt piled high. Just as spring is on the brink of pushing another winter from our memory, the salt mines have apparently turned the corner on earlier supply chain issues. Upon returning home my curiosity, and a lack of having anything important to do in #Retirement, prompted me to look at sources of road salt. I kinda knew it was mined in Ontario, because of Windsor Salt in (checks notes) Windsor. But I was surprised that Canada was a salt powerhouse in terms of production, and that the largest salt mine in the world is in Goderich, Ontario. More accurately, over 540 metres below the prettiest town in Ontario and extending 3.7km under Lake Huron.
