The group had started out on Wednesday, aiming to reach Elsay Lake by following the standard route from Seymour, but soon found the hot temperatures pushed them to exhaustion. They camped overnight and changed plans to take the Old Elsay Lake Access Trail toward Deep Cove to avoid having to regain the elevation to get back to Seymour, but soon found significant amounts of blown-down trees on the lesser-used trail.

Then, disaster. The group broke ground on a wasps’ nest, with one hiker suffering more than 20 stings to his body. He wasn’t allergic, but with the amount of venom he had absorbed, his symptoms meant he was unable to continue.

The group used antihistamines to stabilize his condition and called North Shore Rescue for an extraction.

And they are fierce this year,” Maria Masiar, a training officer with Lions Bay Search and Rescue, said earlier this week. “According to B.C. pest experts, a relatively mild winter followed by an early, warm spring allowed more queen yellow jackets to survive hibernation and establish new colonies. With a longer growing season, those colonies have had more time to expand, resulting in larger, more defensive nests.”
