It's a steep pull up Walsgrove Hill from the north, and in the winter it will be slippery and muddy due to the activities of the sheep that live in this field. However, it offers fine views across to the clocktower and beyond.

A real picturesque old mill, and the Geopark Way affords a really good view of the weir and house from a number of angles.

View to the West The lower part of Walsgrove Hill and the hill on which Abberley clock tower stands are Silurian siltstone. The valley of the River Teme cuts into soft mudstones of the upper Silurian Old Red Sandstone with the harder sandstones of the lower Devonian Old Red Sandstone forming the Bromyard plateau. The low hummocky ground at the base of these hills is underlain by Carboniferous age Coal Measures rocks. These form the southerly tip of the Wyre Forest coalfield. Coal was mined here until the early twentieth century. To the north west, the Clee Hills are also formed of Carboniferous rocks. A molten layer of rock pushed between the layers and formed a hard black dolerite rock, the Dhustone, which slowed the erosion of these still prominent hills and is quarried for roadstone to this day.

Prior's Mill is a former seventeenth century timber-framed water mill, with twentieth century alterations, and now used as a private residence. Next to it is a very high weir on the Dick Brook. There used to be several mills on this stream long ago.

Geological overview Just south of Stourport a magnificent river cliff of fine grained red sandstone is seen. Although mainly homogenous in terms of geology, there are white streaks and thin bands of coarse material running throughout the section. The soft sandstone of Redstone Rock is easily carved and there is evidence of human-made habitation in the cliff face since Stone Age times. The caves that can be seen today were mostly made in the 12th century, when a hermitage was established there, conveniently located for the hermits to be on hand to offer blessings and prayers for passers-by in return for alms. It was said to house up to 500 men, who may have also manned the ferry crossing, which was there due to the presence of a ford until the river was dredged. The caves were later used as domestic dwellings and were inhabited almost continuously until the mid twentieth century. Source: Geopark.org

Shavers End Quarry is one of many quarries in the area located on the Abberley Hills, where the limestone is a sought after material for lime kilns, construction and the aggregates industry. Quarrying activity at Shavers End Quarry has sliced through the North West corner of Abberley Hill, providing a geological cross section for people to study the structure of the area in detail. The scale of the site, partnered with the bare rock faces allows visitors to fully appreciate the complex tectonic history of the area. Within the quarry there are two distinct rock formations exposed; the Lower Ludlow Shales Group and the Aymestry Limestone Formation. The Lower Ludlow Shales Group is the lower of the two units and consists of a series of siltstones and bluish grey mudstones. These rocks can be best seen at the southern end of the quarry, as well as on the eastern banks of the quarry lakes. The Aymestry Limestone is a blue-grey, nodular argillaceous limestone and forms the main rock face that extends along the western side of the quarry. The limestone is shaly and impure and notably contains a thick band of bentonite. Shavers End Quarry sits variably in the hinge zone and on the overturned limb of a large fold. The Lower Ludlow Shales and Aymestry Limestone at this locality are upside-down, suggested by the wrong-way-up orientation of fossils and other sedimentary structures. The age of folding has been the subject of much debate, with many different interpretations; it may have formed during the Variscan Orogeny (~300 million years ago); others suggested that folding occurred during the earlier Caledonian Orogeny (390 million years ago). However it is generally agreed that folding was instigated by thrust faulting on the East Malvern Fault system. This site is part of the Community Earth Heritage Champions Project.

What he said ^^^^^^^

Just south of Stourport-on-Severn, Redstone Caves are made from Triassic sandstone. Carved out in the 12th century and then home to a hermitage, it seems extraordinary today that once up to 500 men lived here. The Geopark Way, a long-distance footpath specialising in geological marvels in the area, runs unsurprisingly right past these caves.
