Saturday’s column described “winter count,” by which Native Americans chronicled the winter season.

During harsh winters, tribes hibernated and sketched images of battles, deaths of leaders and extreme climate conditions.

In 1686, John K. Bear noted, “Ice all over the land.” In 1711 Batiste Good journaled, “Four lodges drowned winter” and Ben Kindle reported in 1773, “Even the dogs got snow blindness.”

The Native American American Horse catalogued events from 1789 to 1791, including, “They could not hunt on account of the deep snow.” Floods in 1825 to 1826 found authors reporting, “Missouri floods, kills 30 lodges.” These entries suggest that Native American winter counts contain valuable climate records
