Dig for Petrified Wood

Home » Arizona » Dig for Petrified Wood

You’ll be digging for and collecting Petrified Wood in Holbrook, Arizona at the Lazy B Ranch.

This location has been written about in rock & mineral magazine and there are multiple YouTube videos showing ordinary rockhounds collecting beautiful Fire Agate nodules.

You’ll spend most of your time digging for and identifying pieces of petrified wood.  Most of the holes are 2 to 3 feet deep and you can find a pre-dug hole to take over.  You’re going to have a ton of fun at this location and come home with quite a few pieces of petrified wood.

Once again, this is an excellent location for families and junior rockhounds.

Keep reading below to learn more about what to bring, clothing types, and driving directions.

Petrified Wood

Petrified wood is a preserved section of a tree trunk or limb in which minerals have replaced its organic material.  The original shapes and patterns of the wood are maintained during the process and the wide range of colors comes from trace minerals.

For example, red, brown, and yellow are caused by iron oxides.  While trace amounts of manganese can produce pinks and oranges. Purple and blue are caused by manganese dioxide and green can be attributed to iron, copper, cobalt, or chromium.
