April - May

The Iroquois Midwinter Ceremony, in which old fires are extinguished and new fires are lit, and the Hopi Holy Cycle, in which the changing of the seasons and the nature of the Hopi sacred universe are celebrated, begin in January and February, but the dates of observance vary by tribe. It is also the season of K’aliyee, the time of the north wind that blows off glaciers and icecaps that linger from the last ice age.

March and April mark the season of the Eagle Dances, when people of the Arizona Pueblo tribes dance to dramatize their communities’ relationship with the Sky-World. This month is also known as Xsaak, the season when candlefish swarm and members of the Nisga’a tribes catch these fish, dry them, and render them into oil for lamps.
