Understanding the Archaeological Excavation Method From Dalziel And Pascoe The Dig
The Dig is the eighth novel in Reginald Hill's Dalziel and Pascoe series. When it was adapted for television, the story centered on an archaeological investigation in the Yorkshire Dales. What made it interesting wasn't just the murder mystery — it was the actual excavation methods shown, which were closer to real UK archaeological practice than most people expect from a police drama. The process involves test pit evaluation, stratigraphic recording, soil sampling, and dealing with weather, land access, and the planning system. I spent a few summers on volunteer digs in the North Yorks area and I can tell you the show got more right than it got wrong. Here's how the work goes. First, you get a report of finds or a planning condition that requires evaluation. In the novel, the trigger is human remains turning up during groundwork. In practice, it's usually a metal detecting find, a planning application, or a known site under threat. The first step is a test pit survey. You dig small holes — typically one metre by one metre — at regular intervals across the area. The goal isn't to excavate the whole site. It's to understand what's there before committing to a full dig. Each test pit is recorded using context sheets. Every layer of soil is a context. You number them, describe them, sketch them, photograph them. The sequence matters because it tells you the order of events. A cut filled with dark organic material means something was dug in and left to rot. A layer of fired clay could indicate a hearth or a collapse. These details don't always jump out at you. They reveal themselves slowly, usually when you're tired and it's raining.
Soil sampling comes next. You take samples from each context for flotation, environmental analysis, and dating. Flotation separates organic material from soil using water. Charred seeds, bone fragments, and carbonised plant matter float to the surface while the heavier soil sinks. That's how you get evidence of past diet, fuel use, and agricultural activity. Bulk samples are also taken for fabric analysis if pottery is present. I learned the hard way that the most frustrating part isn't the digging. It's the paperwork. An archaeological excavation produces far more documentation than material evidence. A single season of work can generate hundreds of context records, site plans, photographs, and sample logs. The physical trench might be three metres by ten metres. The archive file ends up being dozens of boxes. If you don't get the recording right in the field, the rest of the process falls apart because you can't reconstruct what happened without solid primary records.
The Practical Side Of Running An Evaluation Dig
When you're actually supervising a test pit programme, a few things separate a decent evaluation from a wasted weekend. The trench positioning matters more than people realise. You want your test pits distributed according to the question you're trying to answer, not just randomly spread out. If you're looking for a boundary ditch, you need to intersect it. If you're checking for buried soil, you need even coverage. The distinction changes where you put every single hole. Weather is the biggest variable. Rain fills trenches. Again and again. If you dig a trench on a Friday and it rains overnight, Monday morning means you're bailing water before you do anything else. I once spent forty-five minutes with a small pump and a bucket before I could even see the bottom of a test pit that was supposed to be two metres deep. The water table rises fast in the Yorkshire Dales, especially after heavy rain. You plan around that. You don't start a full excavation before checking the forecast for more than forty-eight hours ahead. Another thing nobody tells you: contamination is everywhere. Modern debris — cigarette butts, plastic, nail shards, wire — sits on or just below the surface and gets mixed into older layers if you're not careful. The boundary between recent soil and archaeological deposit isn't always visible until you hit it. I've seen experienced diggers pull a medieval shard from a layer that turned out to be Victorian garden turbation. You have to prove the context is secure, not just assume it is.

What The Novel Got Right And Where It Took Liberties
Reginald Hill was careful with the archaeological detail. The test pit methodology, the context recording system, the emphasis on stratigraphy over treasure hunting — all of that reflects genuine UK archaeological practice. The way the characters deal with the discovery of human remains also follows the proper procedure: stop work, secure the area, contact the coroner and the police, let the investigation proceed through official channels. The dramatic compression is where fiction takes over. In the book, the investigation unfolds over days. In reality, the period between finding remains and getting answers stretches much longer. DNA analysis, isotopic testing, radiocarbon dating — these take weeks or months. The pace of a police procedural doesn't match the pace of archaeological science. But the fundamentals are there. The stratigraphy is treated with respect. The people doing the work understand what they're looking at.
Where The Process Breaks Down
I need to be blunt about the limitations. Test pit evaluation only samples a small percentage of a site. Even with the best grid spacing, you're looking at maybe five to ten percent coverage. You can miss features entirely. A hollow, a posthole, a shallow ditch — if your test pit doesn't hit it, it stays invisible. This is why evaluations sometimes lead to full excavations anyway. You find something in the test pits and then you need to expose it properly. Another problem is the bias toward visible features. Stratigraphic recording works brilliantly when layers are clear. In practice, soil conditions can make boundaries ambiguous. A clay layer blending into a silty clay layer doesn't always have a sharp line. You make a call, but calls get debated later. Review panels, peer review, publication — everyone has a different opinion on where one context ends and another begins. This isn't a flaw in the method. It's just how soil science works. And then there's the planning constraint. In England and Wales, most archaeological work is driven by planning law. Section 61 of the Planning (Listed Buildings and Conservation Areas) Act 1990 and the National Planning Policy Framework set the rules. You can't just dig anywhere. You need permission. You need funding. You need a written scheme of investigation approved by the local archaeology officer. This protects sites, but it also means a lot of legitimate questions about a location never get answered because the resources aren't there. The system works for sites under development pressure. It leaves a lot of rural and historic landscape unexamined.
If You Want To Get Involved
The Yorkshire Dales has a active archaeological community. Local groups run excavations every summer. The Yorkshire Archaeological Society, regional trust groups, and university field schools all accept volunteers. You don't need a degree. You need willingness to learn the recording system and show up on time. Training is usually provided on site. The first day is mostly about understanding context records and how to read a soil profile. After that, you're digging and recording like everyone else. The best way to understand what Dalziel And Pascoe The Dig depicts is to spend a weekend on a real test pit evaluation. The method is straightforward. The execution is where the difficulty lives. You'll leave knowing more about soil, history, and your own patience than you walked in with.
