King Kong height

The altar stood twelve feet above ground level, but the enormous eyes looked down at her. With a questioning grunt, the great beast bent over her. High up on the Wall the islanders fell silent, their pointing arms again motionless.

Driscoll shook his head as they started off again. “I still can’t believe it. I got a fair look. I saw that thing from only the knees up because he was standing on the downside of that slope. Its head was squarely in line with the top of those pillars, and that’s twenty feet above the ground if it’s an inch.” He shivered. “Kong is the size of a small mountain. He must have left a trail we can follow. Look for broken branches, footprints, anything.” Immediately he set off with the others following behind, their flashlights scanning the surroundings.

Her uneasiness began to give way to terror. She forced herself to sit up and her head began to spin, not only because of weakness but also because of a shocking realization: she was thirty or more feet off the ground, perched in the broad notch of a once mighty tree. It was old and gnarled, and felt solid enough to have been rooted there forever. She was utterly alone. How could she possibly have gotten here?
…
The giants separated and stared each other down for an instant. Each refused to give way; each was unaccustomed to being resisted. Kong arched his broad back and rose higher than Ann’s perch. He beat his chest in defiance. The great saurian bobbed for a moment, feinting to one side, and then pressed an attack with the swiftness of a striking snake, mouth gaping, teeth flashing.

Doc studied the old woman for signs of mental instability.
“It would take a creature taller than four men to accomplish that feat of strength,” he pointed out. “Perhaps taller than five men.”
“Kong,” the old woman said seriously, “is taller than ten men!”
That, of course, was ridiculous. Kong would have to stand fifty feet high.

Doc had learned to read sign like a Red Indian. He began looking for subtle but telltale indications of tracks. He quickly found them.
Grass had been crushed and trampled in spots. The spots were very large. But studying them formed no clear impression in his mind. Mentally, he attempted to fit the footprint of a gigantic ape into these flat depressions. His calculations suggested an ape of incredible proportions, possibly twenty feet tall.
Doc dismissed these calculations out of hand. An ape of a dozen feet height was fantastic enough, but he had been half-willing to entertain it. But nearly twenty—? It was ridiculous on the face of it.
Still, facts were facts and spoor, spoor.

In one muddy patch, he came upon a footprint.
The outline was simian, fringed with striations that suggested that the extremity that made the impression in the mud was extremely hairy, in a coarse way.
The footprint was not new. Rainwater had collected in it. Yet the size of the depression was immense, titanic.
Trilling this time from sheer surprise, Doc Savage approached the thing, walking around it carefully. The crater measured over six feet long and half as wide. The big toe was larger than a grown man’s head.
Mentally, Doc Savage calculated the height of the creature that had left that track and shook his head slowly as if in disbelief. All the while his trilling ranged the scale, all but unnoticed by him.
“It would have to be almost as tall as Alfred Bulltop Stormalong!” Doc whispered to himself.
Doubt tinged his vibrant tone. Kneeling, the bronze man touched the fringes of the track, examined the toe print for whorls or lines, such as would be found on any footprint this human-seeming. It was obvious that Doc doubted the validity of the impression—was searching for clues to suggest that it was man-made, a trick of the Dyaks or or other natives. But every indication showed that here was the footprint of an ape or gorilla that stood no less than twenty feet tall, and probably taller! “Kong,” breathed Doc, stifling his trilling.

After several minutes of study, Doc Savage realized that he did not know into what category of animal to classify Kong. He belonged to no known genus or species. That he was an anthropoid ape was undeniable. But no ape stood twenty-five feet tall—which was Doc’s final estimation of his height.
