The Standedge Tunnels () are four parallel tunnels through the Pennine hills at the Standedge crossing between Marsden in Kirklees, West Yorkshire and Diggle in Oldham, Greater Manchester in northern England. Three are railway tunnels (containing the Huddersfield line) and the other is a canal tunnel. Before boundary changes in 1974, both ends of the tunnels were in the West Riding of Yorkshire. The canal tunnel on the Huddersfield Narrow Canal was authorised by an Act of Parliament on 4 April 1794. Construction of a 5,451-yard (4,984 m) tunnel began months later. Within two years, cost-saving measures pushed back its completion date and progress was slowed by water levels much greater than had been expected. It proved difficult to secure skilled help, some tenders went unanswered and Benjamin Outram withdrew from the venture. In 1807, Thomas Telford drew up a new plan for its completion. In 1811, the tunnel opened. It is the longest and oldest of the four Standedge tunnels and is the longest, highest, and deepest canal tunnel in the United Kingdom. Having been closed to all traffic in 1943, the canal tunnel was re-opened in May 2001. The first, single-track railway tunnel, built for the London and North Western Railway (LNWR) on its line between Huddersfield and Manchester, was completed in 1848. It proved to have insufficient capacity and a second, parallel, single-track tunnel was opened in 1871. The LNWR opened a third, double-track tunnel in 1894. Only the double-track tunnel is currently used for rail traffic; the other two are intact but disused. All four tunnels are linked by cross-tunnels or adits at strategic intervals which allowed the railway tunnels to be built without construction shafts and allowed waste material to be removed by boat. The Standedge Tunnel Visitor Centre, at the Marsden end, is a base for boat trips into the tunnel and has an exhibition depicting the different crossings.

Standedge () is a moorland escarpment in the Pennine Hills of northern England between Marsden, West Yorkshire and Diggle, Greater Manchester. Standedge has been a major moorland crossing point since Roman times and possibly earlier. From east to west, Standedge is crossed by five generations of road crossing, the earliest a Roman road from York to Chester and the latest the A62 road. The Huddersfield Narrow Canal and the railway line from Leeds to Manchester pass underground in the Standedge Tunnels. The Pennine Way long-distance footpath passes through Standedge in a north–south direction along the Pennines. Much of Standedge is in the National Trust's Marsden Moor Estate. Administratively, Standedge is split between Kirklees and Oldham.

Marsden railway station serves the village of Marsden near Huddersfield in West Yorkshire, England. The station is on the Huddersfield Line, operated by Northern and is about 7 miles (11 km) west of Huddersfield station. It was opened in 1849 by the London & North Western Railway and is the last station before the West Yorkshire boundary with Greater Manchester. The station is operated by Northern Trains, but only Transpennine Express trains call here.

Bank Bottom Mill, later known as Marsden Mill, was from 1824 an important centre for the production of woollen cloth in Marsden, West Yorkshire, England. Originally a fulling mill, Bank Bottom Mill reached its heyday in the late nineteenth and early twentieth centuries under the ownership of the Crowther family, in particular John Edward Crowther, a businessman and philanthropist. However, the cloth industry declined in the late twentieth century, and production of woollen cloth finally ceased in 2003.

Butterley Reservoir is a reservoir located near Marsden, West Yorkshire, near the Peak District National Park boundary. It was completed in 1906. The reservoir is known for its long stepped spillway, which is grade II listed.The reservoir contains 1,607,385 cubic metres (56,764,300 cu ft) of water when full, and drains a catchment area of 1,583 hectares (3,910 acres).

Marsden is a large village in the Colne Valley, in the metropolitan borough of Kirklees, West Yorkshire, England. It is in the South Pennines close to the Peak District which lies to the south. The village is 7 miles (11 km) west of Huddersfield at the confluence of the River Colne and Wessenden Brook. It was an important centre for the production of woollen cloth. In 2020, the village had an estimated population of 3,768.

The A640 is a road in England which runs between Rochdale in Greater Manchester and Huddersfield in West Yorkshire. The road's most westbound point as on the edge of Rochdale town centre, at the junction of Drake Street and Manchester Road (A58). From here, the road runs eastward through: Newbold Belfield Firgrove Milnrow Newhey Ogden Denshaw Buckstones Deanhead Scammonden Outlane Huddersfield (Salendine Nook, Oakes and Marsh)The road eastbound point is at the Trinity Street junction with the A62 at Huddersfield's town centre ring road (Castlegate). The A640 links both Rochdale and Huddersfield with the M62 Motorway with the road meeting the Motorway's junction 21 (Milnrow for Rochdale) and junction 23 (Outlane for Huddersfield). The road is often closed during periods of snow due to its remote nature over the Pennine hills. The road is known as New Hey Road between Marsh, in Huddersfield and the West Yorkshire boundary. In Greater Manchester, the A640 road names include Huddersfield Road, Rochdale Road and Milnrow Road.

The Wessenden Valley is a moorland valley in the Dark Peak, immediately south of Marsden in West Yorkshire, England. The name Wessenden derives from Old English and means the 'valley with rock suitable for whetstones'. The valley was formed by retreating glaciers at the end of the last ice age and continues to be cut by the Wessenden Brook a tributary of the River Colne with a catchment of 6.28 square miles (16.27 km2).The valley is in the Marsden Moor Estate and occupied by four reservoirs, namely Wessenden Head, Wessenden, Blakeley and Butterley, the largest. The Kirklees Way and Pennine Way long-distance footpaths follow the valley. The upper part of the valley near Wessenden Head is managed by the National Trust as part of the 5,000-acre (2,000 ha) Marsden Moor Estate.Butterley Reservoir's spillway, the only one of its kind in England, was a Grade II Listed structure until Yorkshire Water renovated it using concrete after winning a case on appeal.

Deanhead Reservoir is a reservoir near Scammonden, in the metropolitan district of Kirklees, West Yorkshire, England. It is named after Dean Head, a village that was mostly submerged during construction of the dam. Construction started in 1838 and it opened a year later, almost 140 years before Scammonden Reservoir (its downstream neighbour) was opened in 1971. Water flowing out of Deanhead forms Black Burne Brook which now feeds into Scammonden Water. Deanhead reservoir was originally constructed to supply water to the factories in the Blackburn Valley that was downstream of the reservoir. During the 1995 drought, the outlines of foundations of buildings in the village were visible. Deanhead also is the name of a Pennine pass to the south of the reservoir, which carries the A640 from Huddersfield to Denshaw, following the course of a Roman road.

Stott Hall Farm is a farm located between the eastbound and westbound carriageways of the M62 motorway in Calderdale, England. It is the only farm in the UK situated in the middle of a motorway and was built in the 18th century on Moss Moor. It lies south of Booth Wood Reservoir where the carriageways are separated between junctions 22 and 23. The road divides for much of its length between the Windy Hill and Deanhead cuttings because of the surrounding geography but a myth persists that it was split because the owners Ken and Beth Wild refused to sell.Sally Boazman, BBC Radio 2's traffic reporter and CB radio users nicknamed it the Little House on the Prairie. It is separated from the motorway by crash barriers and a fence to keep livestock in and prevent out-of-control vehicles crashing onto the property. It is one of the ten best-known sights on the motorway network. It was the subject of a BBC Radio 4 documentary, a Yorkshire Television documentary and a short film.

Booth Wood Reservoir is a man-made upland reservoir that lies north of the M62 motorway and south of the A672 road near to Rishworth and Ripponden in Calderdale, West Yorkshire, England. The reservoir was approved for construction in 1966 and completed in 1971. It supplies water to Wakefield. The reservoir dams the Booth Dean Clough watercourse and takes water directly from the surrounding moorland. It has a plain concrete crest on the dam head which is straight and extends to a length of 1,150 feet (350 m) and a height of 157 feet (48 m).In 1995 a long dry spell in the summer created a larger than normal abstraction of water from Booth Wood creating the need to transport water into the reservoir as stocks ran very low. Road tankers carrying fresh water were despatched from Selby in North Yorkshire and Kielder Water in Northumberland to bring water for offloading at Booth Wood. At the height of the operation, 700 tankers delivered 70,000 tonnes (77,000 tons) of water a day to the reservoir which then fed other reservoirs in West Yorkshire.On 14 August 2016, the A672 road which runs along the northern edge of the reservoir was closed whilst police searched for a driver and car that had plunged off the road and into the reservoir. The driver was believed to be the only person in the car and the search operation involved helicopters and underwater divers. The search resumed the next day when a man's body was recovered.

Castleshaw is a hamlet in the Saddleworth parish of the Metropolitan Borough of Oldham in Greater Manchester, England. It lies amid the Pennines, 2.4 miles (3.9 km) north of Uppermill, 3 miles (4.8 km) west-southwest of Marsden, and 5.3 miles (8.5 km) east-northeast of Oldham. Historically a part of the West Riding of Yorkshire, Castleshaw is most notable for the Castleshaw Roman fort, the remains of an ancient castrum. There are two reservoirs, Castleshaw upper reservoir and Castleshaw lower reservoir. In 2016, United Utilities reinforced the walls on the lower reservoir but had to drop water levels by 1m.
