For earth day I wanted to write about Hah-nu-nah or Mikinoc Waajew, an Anishinaabe and Iroquios spirit of the earth.
When Sky Woman fell to earth, there was no land. All the animals of the water took turns trying to bring mud up from the bottom of the ocean. When Muskrat dived, he reached to bottom but drowned, using the mud in his paws the other animals placed in on Turtles back creating land for Sky Woman to rest on.
World turtles are also present in Chinese and Dharmic religions.
