Rock feature vocabulary

Lately I've found myself struggling to find words to describe certain rock features, so I thought it'd be neat to see what terms are out there. I'll get us started with a brief list. I'm looking more for words that describe the features as opposed to moves or movements. Here goes:

arete, col, dihedral, corner, (finger, hand, fist, tips) crack, offwidth, (squeeze) chimney, flake, fin, roof, bulge, bump, ripple, tufa, sloper, jug, nubbin, pinch, hueco, dish, pocket, horizontal, face, ledge, incut, flare, tower, column, undercling, slab, shelf, ridge, block, chockstone, slot, runnel, edge, chickenhead, crystal, pin scar, ceiling, seam, ramp, overlap...

Positive, lip, downsloping...

Edit: Horn

rail, pod, dike, intrusion, knob, V, trough, water streak, crimper, book, buttress, pillar, hole, tunnel, arch, cave, niche, alcove, trihedral, ...

I prefer to call slabs underhangs.

Slimper

thumb-catch, bucket, divot, splitter, open-book, sidepull, weakness, headwall, steep

Stembox. Yep, only one to add.

Diving board

choss, cut, chip(ped), rotten, exfoliating, plate, dome, anticline, layer, tier, shallow

Notch, groove...

Also - to me these can kind of be features - stance, stem

Great! Slimper is awesome.

buttress, overhang, knife edge, mono, break, crag, rut, furrow, spike, fissure, step

Damn, Larry s keeps beating me to the punch... all I got left is apron, tooth, tongue.

rooflet (I think its a roof less than 4 feet. I think it comes from the Gunks but never been there)

knob, nipple, pod, ripple, mail slot

What would you call this?

The rightmost feature

I'm talking where there's a distinct layer of rock pasted to the main face so it makes a little mini dihedral, but not detached enough to be a fin or flake. Also the layer is parallel to the main face, and not big enough that you'd call it a corner. Sometimes there can be a deep crack between the face and the layer.
Overlap seems like it might work, but I feel like there's a better term out there.

I'd call it a flake. Just a big ass one.

My contribution: Boss.

Pretty sure the Vegas folk call this type of rock varnish, but what about the individual blocks? Armor plates? Shingles? Shake?

And those sections of sharp tiny sharp limestone spikes? I think "prickles" works well.

What is a boss or a tongue?

A "tongue" of rock hanging down from above. Just pulled on one today. I've heard the little limestone spikes called velcro, saw some of that today as well.

Tongue is legit to my parlance. It's basically an upside down horn, or, if you will, an extruding tongue-shaped piece of rock, like the Rolling Stones graphic.

How about tafoni? That is a sandstone feature.

popcorn

water groove

tube

incipient seam

rail

chip

suitcase handle (they do exist, mostly on limestone)

Porphyritic, graphic, variolitic, trachytic,phaneritic... All great ways to describe rock (igneous) features.

Sometimes "tafoni" is used for honeycombed granite as well.

"Patina" has not been mentioned yet.
