This is an Earthcache, there is no physical container. You need to answer the questions below!
Holy Trinity Church is in Warrington town center. The church is recorded in the National Heritage List for England as a designated Grade II listed building and is still an active Anglican parish church in the diocese of Liverpool, the archdeaconry of Warrington and the deanery of Warrington.
Sandstone
Sandstone is a sedimentary rock composed mainly of sand-sized silicate grains. Sandstone is composed of quartz or feldspar, because they are the most resistant minerals to weathering processes at the Earth's surface. In Cheshire a lot of the sandstone is red due to it containing the mineral iron oxide.
Cross Bedding
Cross bedding is layering within a sandstone rocks, these are at an angle to the main bedding plane.
Cross bedding forms during deposition on the inclined surfaces of bedforms such as ripples and dunes; it indicates that the depositional environment contained a flowing medium of water or wind.
Graded bedding
A graded bed is a bed characterized by a systematic change in grain or clast size from bottom to top of the bed. This most commonly this takes the form of normal grading, with coarser sediments at the base, which grade upward into progressively finer ones.
Graded beds generally represent depositional environments which decrease in transport energy (rate of flow) as time passes, but these beds can also form during rapid depositional events. They are perhaps best represented in turbidite strata, where they indicate a sudden strong current that deposits heavy, coarse sediments first, with finer ones following as the current weakens. They can also form in terrestrial stream deposits.

Questions
- Look at the sandstone, what type of bedding do you see here?
Near the corner of the building away from the door has some good examples
- Are the bedding lines fine or large?
- Take a photo by the church, you don’t need to include your face, you could just take it with your caching name on a piece of paper.
