Radials on/in the ground aren't resonant. Most of the current in them
will be close to the tower regardless of the length of those radials so
put down as many as you can at whatever length they come out which will
be better than no radials.

With that info I might be inclined to use the same amount of wire and put down
5 times as many 20 foot radials in that 75 degree span.
Obviously there would be some amount of bend which would have no effect.

An experienced local MW broadcast engineer and low band ham, VE6LO now SK,
did some experiments with radials on a 160m vertical he had with a yard
that also had obstacles. Using a RF current meter (similar to the MFJ 854
I expect) he came to the conclusion that if a radial had to be bent to go
around an obstacle, you might as well not bother - as he found very little
RF continued past the bend.

I would stake them down at base of wall, go up and over the wall,
stake them down on other side and continue out.

Now that the glacier has receded from Wisconsin, I want to put in
radials around my 80' AN Wireless tower (free standing no guy wires).
About 20' out on an arc of about 75 degrees I have an old stone wall.
It's not high but has huge glacial boulders which really can't be
moved. My radials will be about 100' long (some a bit longer some a
bit shorter). They will be buried using a trencher designed to bury
invisible dog fence or lawn sprinkler pipes. I will likely go down ~3"
using 15 gauge solid enamel copper wire (got it an auction of a
transformer mfgr going out of business).
My question is: should I run the 20' radials out and end them at the
wall, and the radials at the end edges of the wall (either side of the
75 degree arc) connect those to a wire (forming a chord - parallel to
the far side of the stone wall) and then connect radials to this cord
and continue those radials out another 80-100'?
Hard to explain without a drawing. I would also mention that the
ground falls away from the tower in this direction, probable down 25'
from the base of the tower. This is into a woods and the soil is very
rich and should be a good conductor.
