blog of the State Geologist of Arizona
Thanks for the link. My brother and I live in the Phoenix metro area and have discussed new places to explore. We know we need to begin driving a little further at this point to reach new hiking destinations. This is another idea for us to consider.
FYI - old blog. I went by the AZGS Bookstore this week (03/2011) and they had no idea about this map. Gonna try contacting the Town of Marana directly.
We've had trouble getting and keeping these in stock, but our bookstore manager tells me that Marana is shipping us a new supply.
