PLEASE NOTE THAT WE DO REQUIRE YOU TO GO TO THE RELEVANT PLACE IN QUESTION 4 AND GET THOSE COORDS!!As of 31st August 2017 there are notices telling you not to bring dogs as there have been incidents with dogs chasing sheep. Please do not take a dog with you to complete this cache!!!!If you don't have the time for this section, then there is the Virtual cache nearby! This cache requires a fair amount of time and walking so please allow time to complete. the distance is just on 3.5miles. Thanks. 
To claim this earthcache as a find you must submit your answers to ALL the questions. Thank you. Failure to submit answers will result in logs being deleted without notice.
I try to reply to all emails quickly but am very busy and sometimes this may take a week or so.
Please answer these questions :-
1. The coordinates take you to the two stones which were once in the old car park before the new visitor centre was opened.
Let us know what types of rock the stones are and describe each stone (size, texture, colour), clearly referring to the larger and smaller stones. They are two different stones!!!!! ........
2. At N 51° 10.758 W 001° 49.516 you will find the sarsen heelstone which stands adjacent to where the pavement used to be! Try and estimate the weight of this stone given that 1 cu.ft weighs 154lbs.
PLEASE NOTE THAT IF YOU ARE NOT ABLE TO ACCESS THIS STONE THEN THIS QUESTION CAN BE ANSWERED BY RESEARCHING ON THE INTERNET.....
3. You need to go across the fields to the notice board at N51° 10.956 W001° 49.180 which tells you all about The Avenue.
What are the 15 words immediately below "STONEHENGE AVENUE".... beginning with "In front of...........Please let us know what this sentence reads.
4. Walk from there towards the animal trough (a small structure for animals to drink from) and then turn around and head back in a SW direction and email us the coords where Stonehenge becomes visible.
The distance from the centre to the Henge is about 1.8miles (as the crow flies). The total distance now to allow for doing this earthcache is about 3.5miles. This is reflected in the Difficulty rating so please do allow plenty of time to complete the tasks.
5. Optional - but would be appreciated - is a photo of your caching group with Stonehenge in the background.

Stonehenge is one of the most famous sites in the world. It is composed of earthworks surrounding a circular setting of large standing stones. New research has cast fresh doubt on the journey which the Stonehenge Bluestones took from Pembrokeshire to the site of the pagan monument.
How the stones ever got to Stonehenge has long been a mystery. The monument has been studied over and over again by archaeologists and geologists but many questions still remain. It has been concluded that the rocks at this prehistoric monument did not come from the local area owing to the composition of them. Salisbury Plain is formed of soft chalk which was deposited during the Cretaceous period whereas the stones that form the monument are of two rock types: sarsen sandstone which is a sedimentary rock and bluestone which is an igneous rock.
The fact that the two types of rock are different to the area in which they have been erected adds the mystery as to how the monument on Salisbury Plain could have been built. Since the 1920s, geologists have strongly suspected that the 'spotted dolerite' Bluestones, which form Stonehenge's inner ring, originated from Mynydd Preseli in the north of Pembrokeshire.
The larger stones that make up the outer circle of the monument and rock beams across the top of the standing stones are made from sarsen sandstone. This was deposited over much of southern England at the beginning of the Tertiary period about 60 million years ago. It is post glacial remains of a cap of tertiary silcrete which once covered much of Southern England. It is a dense, hard rock created from sand bound by a silica cement making it silicified sandstone. Sarsen sandstone is not native to Salisbury Plain and it has been known since the 16th century that the sarsen stones came from near to Marlborough, 19-20 miles away.
William Stukeley wrote that sarsen "is always moist and dewy in winter which proves damp and unwholesome and rots the furniture". However, despite these problems, sarsen remains highly prized for it's durability, being a favoured material for steps and kerbstones.
The smaller stones at Stonehenge are an igneous rock called bluestone. This rock is also not native to Salisbury Plain. Bluestone is so named as it has a blue-grey colour when wet. The bluestones at Stonehenge were placed there around 2300 BC. It is assumed that there were about 80 of them originally, but this has never been proven since only 43 remain. The stones weigh between 2 and 4 tons each.
The term "bluestone" in Britain is used in a loose sense to cover all of the "foreign" stones at Stonehenge. It is a convenience label rather than a geological term, since at least 20 different rock types are represented. A common one, Preseli Spotted Dolerite (a chemically altered igneous rock containing spots or clusters of plagioclase feldspar) is harder than granite. Bluestone tools, such as dolerite axes, have been discovered all over the British Isles. Many of them appear to have been made in or near Stonehenge, since there are petrographic similarities with some of the spotted dolerites there.
The bluestones are arranged in a circle inside the larger sarsen circle. Geologists have used geochemical analysis to match the bluestones to an outcrop located more than 125 miles away at Preseli Hills in western Wales.
These bluestones hold another clue - although geologists have confirmed that they did not form in or near the Salisbury Plain, archaeologists have come across fragments of bluestones in the Salisbury Plain that were in place long before Stonehenge was built. This evidence supports the theory that the bluestones were not transported to the Salisbury Plains by humans, but must have been transported by some other force.
There are two theories that can explain how these sedimentary and igneous rocks came to be at Salisbury Plain. One theory, favoured by archaeologists, is that the stones were transported there by the monument's makers. However, this theory does not explain how the bluestones came to Salisbury Plain since it has been established that they were brought there before any development of the monument started. The second theory is that glaciers transported the stones to Salisbury Plain.
In 1971, a geologist published an article in Nature suggesting that the bluestones are boulders (glacial deposits) which have been transported by glacial movement. Moreover, subsequent geochemical studies have established that the bluestones did not just come from one quarry, but multiple quarries throughout Preselli Hills, some as much as 8-9 miles apart. Geologists conclude that these bluestones must have already been conveniently close to the monument's site, transported there by glaciers.
