The huge canvas of Abraham Lake made for some tricky decisions for Popa. The human-made lake stretches for about 35 km (21.7 mi) and is 1–2 km (1.6–3.2 mi) wide. But he knew the lake would be perfect for one of his portraits.
“To do a work in collaboration with those methane bubbles and just this unbelievable depth of colour of Abraham Lake, is just incredible,” he says.
Popa worked closely with Brett Pawlyk, co-owner and head guide for local adventure tourism company Canadian Rockies Escapes, to find the perfect place on the ice for the artwork.
Pawlyk and his guides are on Abraham Lake almost daily assessing conditions and scoping out the most picturesque spots for tours. They post regular ice condition updates on Instagram and on their website.
How the Abraham Lake ice bubbles are created
“It is a very dynamic place,” Pawlyk says of Abraham Lake. “With the temperature swings, you get different formations in the ice. So, when it's minus 30, you get all kinds of cracks and fractures everywhere that create these beautiful mosaics, and then when it warms up, that expansion and contraction of the ice changes its character as well.”
The phenomenon of the ice bubbles at Abraham Lake happens because of a few very particular ingredients, Pawlyk explains.
First, the glacier-fed lake’s water level drops every spring, baring the lake’s bottom and allowing flowers and other vegetation to grow. As the water levels rise with winter meltwaters, the plants die and decompose, releasing bubbles of methane upwards.
When fall arrives and the surface begins to freeze, the methane continues to bubble up. But now the bubbles get trapped beneath the freezing surface. Bubbles continue to release from the lake floor, freezing in stacks.
