Ignition Component Ignition Component The Ignition Component is a number which relates the probability that a fire will result if a firebrand is introduced into a fine fuel complex. The ignition component can range from 0 when conditions are cool and damp, to 100 on days when the weather is dry and windy. Theoretically, on a day when the ignition component registers a 60 approximately 60% of all fire brands that come into contact with wildland fuels will require suppression action. Ignition normally takes place in the dead component of the fine fuels. Three distinct steps must be considered in this ignition
Mesoamerican Archaic period seasonally by largely mobile peoples in the Early and Middle Archaic periods. Based on the presence of specific plants, the rock shelter was inhabited during the wet season from July to September, then in the Archaic period, around 4700 BCE, from May to October. Some of the earliest known villages appear along sea coasts, specifically the Chiapas and Caribbean coasts. It is likely that the abundant sea and lagoon resources could easily support long-term, year-round settlements, leading people to settle first in these areas. Shell mounds in these areas are highly visible, which likely aided in their identification by scholars.
