Abstract
Abstract A glacial forebulge is a bending‐related upheaval of the lithosphere outside a glaciated area that co‐occurs to the depression of the lithosphere below an ice sheet. The forebulge of the last glaciation attracted attention over more than one century, but quantitative descriptions on the geometry of the forebulge are rare. While many studies mention forebulge dynamics as a possible cause for a certain observation, very few studies provide a detailed and systematic exploration of the forebulge's precise dynamics. That way the forebulge became occasionally a rather mysterious structure with many unknowns. We aim to shed light into the forebulge discussion. After reviewing the history of forebulge research, we outline the theory behind the spatio‐temporal forebulge development including controlling factors, and present forebulge observations in geological and geodetic records of North America and the northern parts of Central Europe. We use a state‐of‐the art finite‐element model that can fit multiple observations of the last glaciation simultaneously, to illustrate forebulge development in North America and northern Central Europe and address the issue of whether the zero‐uplift hinge line is a good indication of the location of the forebulge front. Finally, we discuss effects of the forebulge on the sea‐level change pattern and the evolution of lithospheric stresses, which can induce intraplate earthquakes. We also show that the existence of a glacial forebulge outside the ice margin is not consistent with the assumption of isostatic equilibrium at the Last Glacial Maximum, and there is no strain rate‐stress paradox.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
