Narrative:

After departure (VFR) from grand canyon airport at approximately xa hours local, we proceeded swbnd until we were outside the air traffic area and the sfar zone. We performed a spiraling climb to 11500' (using grand canyon altimeter) for a northbound flight through the dragon corridor. Using visibility references while monitoring 122.75, we proceeded nnwbound in what we thought was the dragon corridor--a current las sectional was used. After reaching the north rim, we believe that we misjudged the corridor location and may have overflown the western and northwestern zone. Perhaps DME/radial information from the grand canyon VORTAC would assist in more clearly defining the precise location of some of the corridors.

Title: REPORTER FLT POSSIBLY ENTERED A FLT FREE ZONE WHILE DEPARTING THE AREA.

Narrative: AFTER DEP (VFR) FROM GRAND CANYON ARPT AT APPROX XA HRS LCL, WE PROCEEDED SWBND UNTIL WE WERE OUTSIDE THE ATA AND THE SFAR ZONE. WE PERFORMED A SPIRALING CLB TO 11500' (USING GRAND CANYON ALTIMETER) FOR A NBOUND FLT THROUGH THE DRAGON CORRIDOR. USING VIS REFERENCES WHILE MONITORING 122.75, WE PROCEEDED NNWBOUND IN WHAT WE THOUGHT WAS THE DRAGON CORRIDOR--A CURRENT LAS SECTIONAL WAS USED. AFTER REACHING THE N RIM, WE BELIEVE THAT WE MISJUDGED THE CORRIDOR LOCATION AND MAY HAVE OVERFLOWN THE WESTERN AND NORTHWESTERN ZONE. PERHAPS DME/RADIAL INFO FROM THE GRAND CANYON VORTAC WOULD ASSIST IN MORE CLEARLY DEFINING THE PRECISE LOCATION OF SOME OF THE CORRIDORS.
