About this guide
A practice website. Wrenlow, its quarry, its walls and its 48 routes do not exist.
Figures
Route lengths, grades and bolt counts are made up within the range of small limestone quarries in northern England. Grade equivalents follow common published tables and are approximate.
Sun times use the low-precision solar position formulas from the Astronomical Almanac for 54.31° N 2.24° W, accurate to about ten minutes. Drying times are a rule of thumb, not a measurement.
