Four 8ft ground rods spaced further apart would be better. Up to 16ft apart
max. Bonded together underground as well.
Add a few more rods, and you could reach the AC panel's ground to bond it
all together. Run at least #2 or better, or better yet 2" or 3" strap. for
the underground buss keeping any corner curves as wide as possible.
Always meet local codes and NEC for minimum # of ground rods and bonding.
Add more as needed.

"Ouch!" is right!
For one thing, the first thing that hit me was that "60 feet"which is
awfully close to a 1/4 wave on 80 meters. Potential problems there? I don't
know. I only suspect.
Is it possible for you to (yes) run say a #00 stranded copper wire from the
panel ground to your station ground, adding other ground rods at places in
between the ends to break up the distances?
Also, it seems to me that one ground rod at the panel is not really enough.
I used three here, but then again, ground conductivity in my area is VERY
poor.
Jim would know far more about this than I do, but if I were in your
position, I think I would try what I suggested above.
