 I will tell you a few facts about agates.  Agates are rarely larger than an adult’s fist.   Agates appear in a variety of colors:  white to gray, red, reddish brown, brown to yellow, blue to purple, and have multicolored bands.  Agates are at a level seven on the Mohs scale of hardness.  They can be scratched by topaz.  Agates are a form of quartz crystals that are too small to see.  
You can find agates all over the country.  In the southern part of Colorado try looking along the Arkansas River.  Agates are also found in the San Juan Mountains. Agates can be found to the west of Teller county in Park county. Look for see through material and bands of color.  Maybe if you’re lucky you can find some agates in your own backyard!
