Dust is made up of tiny, solid particles (“particulate matter”) floating in the air. Dust can be generated and released into the air as a direct result of human activities such as:
- Land development
- Gravel production
Blowing dust so thick that it’s hard to see the mountains would suggest there is a dust problem.
NOTE: Dust particles are illuminated and appear thicker when you are looking towards the sun (typically in the early morning and evening hours).
