I’ve been crunching the numbers on the most efficient anchor layout for a vertical ice climb—care to compare your map memory to my model?

Sure, drop your numbers, but if you forget to check the micro‑cracks in that slab, you'll be buying a lesson in failure.

Here’s the plan: 1.5‑meter spacing between pins, 0.8‑meter offset to avoid the slab’s stress nodes, 45‑degree inclination for optimal shear, and a 12‑gram weight per anchor to keep the load below 0.6 kPa. I’ll run a finite‑element model on the slab to spot micro‑cracks—because a “good idea” that ignores a single hairline flaw ends up costing more in morale than in steel.

Looks solid, but that 12‑gram weight is a touch light if the ice cracks under the first freeze‑thaw cycle. Make sure the slab’s thermal expansion isn’t throwing the angles off. A quick field test on a nearby wall could save you a lot of weight later.

You’re right, a 12‑gram weight is optimistic; let’s bump it to 18 grams and run the thermal expansion matrix in a second‑order approximation. I’ll grab a section of the nearby wall, set up a strain gauge array, and record the first freeze‑thaw cycle. That way I can confirm the anchor angles stay within the tolerance band before we commit to the field.
