I have uploaded a printable single sheet map of Zicafoose Blowhole that can be zoomed to 6400% without loss of detail.
Note: Zoom to 6400% using Acrobat Reader 7 or 8 and 3200% using Acrobat Reader 6.

NOTE: for printing any particular section just zoom in to desired % and then choose "Print" then select "Current View" then select Page Scaling: "fit to printer margins" and it will print that view to the full sheet.
