To make the trip a circle, you can walk back from the Redstone Village triangle park to your car parked here on Hemlock Lane within a short time (ten minutes) along Redstone Road.
Be sure to follow all of New Hampshire's hike safe rules for details see this link. Check here to see if it is hunting season. Even if it is not hunting season, wearing hunter's orange is a good idea. At other times of the year follow guidelines to protect against ticks and insects.
We would like to thank the many people and organizations that helped develop this trail. Please see the credits at the end.

what this pipe for?
need a directional sign here to the crossing on the right
Turn left at the "alien" concrete barrier
If it is clear, look at the details of the raised letters on the rails.
what kind of permission do we need to have folks cross the railroad tracks?
perhaps some kind of ramp system?
need a directional sign here to the left
look closely on the rails for raised lettering
also look at the various parts of the rail system
insert pics of each
an interpretive sign or qr code to a webpage could related the relationship of the railroad to the development of the quarry, see Hounsell, pp. 193+
"In 1880, the attention of George W. Wagg was called to the fine quality of granite which was used in some bridges of Conway."
copy more from Hounsell p. 195 use this instead? or in addition?
"Somewhere between 1876 and 1880, there arose a need for stone abutments for three bridges in Conway... They were made of granite boulders lying handily at the foot of Rattlesnake Mountain. The ease with which this stone was split and handled excited the admiration of the stonecutters and it was not long before this came to the attention of George W. Wagg, general roadmaster for the Maine Central Railroad. He saw great possibilities in the stone because of its color and the fine luster it would take, too."
then map navigation, but also community, it is a memory map drawn by A.J. "Babe" Pennette. (check spelling, ask Ken Rancourt for more info on this).
The image below is a hand drawn map of the area. It can help you navigate through Redstone village and understand the industrial areas on the trail.
insert photos here of the path from the train crossing to NEMBA sign #39
There are a number of potentially confusing twists and turns here.
It is hard to use the NEMBA signage
Should we have a separate set of directional signs?
Could we put our signs on the NEMBA posts?

Rejected, polished green column," pilaster", or better description "engaged column."
flat on one side, designed to go up against a building rather than to stand free. Reportedly it was to have been part of a structure at Grand Central Station, NYC. As recently as the year 2000 there was another rejected, round, polished green column lying nearby close to 17 feet long. It was cut in half in Ringe, NH for the Schiavi Co., owner at the time, and installed on the front corners of the Intervale, NH Post Office. The left hand column reveals an obvious seam which presumably was the reason for rejection.

notice the holes in each end of the engaged column. Later on the trail we will discover the purpose for those holes and see the machine on which the column was turned, shaped.
Next you cross an open field with powerlines

Now to the boiler room seen on the map below.
Two coal- fired boilers and two giant air compressor-steam engine flywheel combinations were originally enclosed within the same building. Boiler fronts are gone and a number of metal parts have been stolen for scrap metal. The boilers provided steam to power the engines which in turn drove the compressors that provided air for pneumatic tools in the quarries and stone sheds. The large air compressors, built by Chicago Pneumatic Tool Co., were installed in 1903 and 1905.

Large CALIX core samples of green granite drilled prior to the last job furnished from Redstone in 1948 by the Swenson and Fletcher granite companies for an addition to the Criminal Courts building in NYC. Conway green granite was specified by the architect, quarried at Redstone and shipped by rail to Concord, N.H. and Milford, M.A. for final finishing by the Swenson and Fletcher companies respectively.
Three thousand and two foot core drilled in 1974-75 for exploration by the US Energy Research and Development Administration. The purpose was to evaluate the heat flow and geothermal potential of the Conway Granite. Secondarily to evaluate the potential source of uranium and thorium assocciated with the Conway Granite. Results did not warrant further exploration. However, there have been further speculations of potential geothermal sources within the Mount Washington Valley.

The next stop after the quarry loop is the site of the old stone shed
Stone shed and blacksmith's forge with fire brick, parts of which have been stolen for scrap metal. The location is in the NNE corner of the original, 500 foot long, wooden stone shed. A cut guy wire from "Matron's" derrick is still visible on the ground while the two photos illustrate what was stolen for scrap metal (2012).

Remnants of "Matron's" derrick, likely with a 90 foot mast and 80 foot boom, was strategically located and able to reach granite blocks coming from the two-way pink quarry tracks, the one-way green quarry tracks as well as any of the lathes. The base plat "socket" is obvious, the boom is mostly gone while parts of the mast remain along with the massive assembly of steel and ten guy wire attachments.
This massive assembly was on the top of the mast. Many of the wooden masts and booms were of Douglas Fur shipped on articulated flatcars from the Pacific North West.
Below is the top of the derrick.
x
Yard area at the bottom of the one-way track from the green quarry. Multiple buildings were once here. Still remaining is the polishing shed with partial roof which could handle a column close to 19 feet long. No longer enclosed lies the large lathe which did the initial "roughing out" of a column prior to polishing. Columns were moved on slings hooked to a derrick and lowered in and out of the lathe building, thus the partial open roof remaining on the polishing shed.
Explore the Lathe building
How to preserve this building and it's contents? Should we contact NH Preservation Alliance and/or NH Dept Historical Resources, HABS/HAER for advice, support? It would be nice to have students do detailed photos and measured drawings, research on the companies involved, etc.

This is a historic photo showing the old rail line
You will be walking over the old train lines that ran up and down the mountain. Here you can see them before the trees grew in.

x
On this route you would walking up the rail that went to a derrick at a T on the edge of the red quarry, seen the picture above between the two large waist piles of broken rock and in the map below.
x
If you take this path, On the right you will see several piles rock
Then come to a T
Option B follow the narrow rail line from the lathe house up to the green quarry seen on the map below.
Another option is to take the old rail line up to the Green Quarry
go around the back of the lathe house and find the rail line/track (fuji8279 +)
We could remove dirt so that the rail can be seen as in the map.
as you follow the tracks on the ground, follow the wires that go into the trees, literally into and through the trees. Actually you will see how the trees have grown around the wires

The following section of the trail guide is a round trip detour to the red quarry and a scurry up to the ledge above.
Note: this is not recommended for inexperienced hikers. It can be risky.
As you move along this path, you will notice the subtle change in color of the stone from "green" to "red"

Soon it splits forks (we took the right, better to follow the left and take next right) need to photo these other trails later.
or should we build this trail safer? or both? as it does give good elevated view of the quarry

Green quarry, full of ground water, at the top of the one-way, winch rail line. Remnants remain of three wooden derricks, an engine house and "tugger" winch (1893) which retracted a rail car from the end of an extensive quarry dump. Parts of two derricks are obvious within the quarry hole while the third, "stiff-leg" derrick was higher up in the back SE corner of the quarry. When viewing the latter remnants one may note an excellent example of a "clovis" arrangement of hardware which is the anchor for a guy-wire attached to the top of a derrick.

The picture below shows more graffiti has been added since the previous visit.
The "Carpenter Shop" a two story building with roof intact however seriously vandalized. Earlier photos show a handsome building which served many purposes including storage of supplies. Carpenters were important workers responsible for ongoing maintenance of many wooded structures as well as crating of finished stone work to protect it during shipping by rail.

This sidetrack was a second set of railroad tracks was covered with asphalt leading into the trees on both sides
notice the cracks in the asphalt under which the train tracks are covered.
This was the "side track" or siding where train cars could be set aside so as not to stop the regular train traffic on the main line.
Below is looking "south" or "east" to the right
This main line runs to Portland Maine, a port of the Atlantic Ocean.
If you look carefully down the track you can see where the siding or side track meets again with the main track.
This line runs (or ws intended to run to (Ogdensburg? the Saint Lawrence? seaway, ck history and include maps of the period and today.
As a result, granite from this quarry could be sent by rail to a port and then shipped by sail and steam anywhere in the world.

In this photo above you can see three different textures of stone finishing.
insert here or later about the tools that shaped the stone?
Just beyond the granite sundial are two slabs of stone engraved with some of the history of Redstone.
While the sundial is highly finished and shows few tool marks, the bench in the foreground here can tell us ...

A couple more images to show where to park, should we delete them? Can we post signs saying where to park and where not to park?
Let's check out this sundial
careful observation, guided discovery, clues, evidence, history detectives
If you look at it from this angle you can see the sundial, the street name signs, and the historic building beyond which served as the store (more on this later).
Notice the base of the sundial is pink granite with a matte finish, that is then surrounded by highly polished/shiney green granite.
insert here pics of the names and the writing on the memorial
If you look at it from the angle below,
The item in the foreground is a sundial that commemorates the names of Redstone veterans from the first world war, 1917-1919.
For more veteran memorials in Conway see this link.
If you look beyond the monuments here in the triangle park, you can see the quarries cut into the hill beyond.
If you look at it from the angle below,
Here is what that view used to look like
You can see some of the derricks used to move the stone blocks around.
Here is a comparable view from today.
Here is a detail of that view
This short, easy walking tour of Redstone starts at this magnificent granite sundial in the "triangle" park and heads northwest to another parking site at Hemlock Lane near Walmart. The trail is a small part of an extensive multiuse trail system.
While relatively short and easy, this tour provides an amazing number of interesting historical features (and views), and if you bike it, lots of action and adventure. At one time there were more than 350 men employed in the quarry operation here.
The first section of this trail guide shows some of the highlights of the trail. After that we get into quite a bit of detail for the planning and implementation of directional and interpretive signage. (until we see this picture above of a large stone sundial again).
(could a simplified drawing/sketch of this serve as a logo for our sign system?)
for directions, a map, location search see this link here.
