June was a popular month for weddings long before the Klondike gold rush. People of medieval times often took their annual baths in May, which meant a bride would still smell fresh in June. To be safe, she carried a bouquet of flowers to hide any body odor. That’s where the custom of carrying a bouquet down the aisle comes from.
Many miners who came north in search of riches may have chosen brides at the beginning of summer for practical reasons. Once the ground thawed, and a miner found a plot that showed promise, he drove stakes into the ground to lay claim to mining rights. By 1897, only one claim per person was allowed in a district.
But a loophole in the mining laws allowed married couples the right to register a separate claim in the wife’s name, thus doubling the amount of land for prospecting. So taking a wife could mean untold riches from the ground.
