I agree. And have in the past often called for just such easy excavation to help answer this 'Avenue stripes' mystery.
But here is the rub. Whether or not other similar solutional stripes exist in the landscape outside the confines of the Avenue, it wont explain why the Avenue stripes align with the center of Stonehenge proper. Such alignment points to the water flow forming these solutional stripes to have been sourced at the center of Stonehenge. And further, to have been structurally confined to flow within the Avenue in a direction somewhat diagonally to the downslope.
All these indisputable 'facts on the ground' can only be explained by my hypothesis:
"Stonehenge at one time was a meltwater retaining basin in a local ice cover. And the Avenue was its main egress channel draining into Avon river below."

If it is important to know if the stripes are or are not associated
with the Avenue, how much trouble would it be to extend, to beyond
the Avenue's ditches (possibly with only a narrow extension) the
excavation of the Avenue that reveals them?
