"Blood on the Arrow" (1964) is a "B" Western, which mixes together several staples of the genre: Calvary, outlaws, saguaro cacti, Indians, gunfights, a trading post, a hottie, a mine and gold. It rips-off blatant elements of "Shane" and transplants them to the Arizona desert, but gets away with it because there are enough differences. It's just severely mediocre by comparison, although Dale Robertson is stalwart as the hopefully redeemable outlaw protagonist and Martha Hyer is a blonde beauty worth risking everything.
Regrettably, there are some "Why sure!" plot problems and what's up with the trap door that's anything but hidden? Also, you'll clearly see power/telephone lines on 3-4 occasions. I'm assuming that the producers felt they'd pass for telegraph lines, which WERE present in 1871 when the story takes place. I'll accept that argument, I guess.
