I've been reading up on this and I wanted to see if my understanding is correct. If ancient river courses are responsible for the soils, does that mean I live on an ancient delta?

Probably not. But water flow may be an important part of the explanation (as ice might be)

Being in England, the birthplace of modern geology, I'm pretty sure there are books and maps about the local geology. Did you try having a look?

Take a look at [this](http://mapapps.bgs.ac.uk/geologyofbritain/home.html) geological map of Britain from the British Geological Survey. Take a look at your local area and maybe edit your question to provide us more detail.

The BGS also have some excellent regional handbooks. They're currently going through republishing them.I don't know the age of the one for your area, but anything in the past 20 or so years is probably good! (some of the recently replaced ones were from the 1940s-60s).

# The geology of local landscapes and small scale features

(Asked by: username_0 on 2016-05-03)

I'm learning geology to understand the processes behind the formation of my local landscape.

I understand the processes behind big features, such as mountains. But I'm struggling to understand the processes behind small local features, such as hills.

I live in Reading, Berkshire, South-East England, with a typical landscape of **rolling of grassy hills** and **clay strata**. Similar to this image below.

**What geological processes would be responsible for the formation of this landscape?**

## Additional Information

**Strata**:

I dug a hole in my garden and found there is a thin layer of soil, then a large amount of clay with a variety of rocks and pebbles.

**Features**:

The main features are a landscape of rolling-hills and grassy plains.

**Question**

What geologic processes are responsible for the formation of these low-hills and clay strata?

Were the hills once mountains, now eroded?
