Farndale Cairn
Examples of well built ones with well placed stones are far less common. Many are placed where they can be seen from a distance, such as the shoulder of a hill. But this one is extremely well hidden and I'm not sure it can be seen from any public path or road. I
Its in Farndale. Its very well built - the stones are carefully selected and placed so that the cairn is a true cone shape. Someone took a great deal of care in making this a nice cone shaped cairn. I'd probably guess its a memorial to a favoured dog..Or perhaps an accident? But who knows?

'Consumption Walls'
the smaller stones gathered from the field, when the process of enclosing land was first commenced.
They aren't too common, and this is the only one I've seen in the North Yorkshire Moors park.
This specimen is at Danby Dale just south of Botton village at NZ 690031

Two Trees growing from one.
Its not rare to see one tree growing from the stump of a fallen tree, but here we have two. One is a Silver Birch and the other is I think a Norway Spruce.

Morse Code by Light.
SECTION 6: FLASHING LIGHT SIGNALING
1. A signal made by flashing light is divided into the following parts:
(a) The call.—It consists of the general call or the identity signal of the station to be called. It is answered
by the answering signal.
(b) The identity.—The transmitting station makes “DE” followed by its identity signal or name. This
will be repeated back by the receiving station which then signals its own identity signal or name. This
will also be repeated back by the transmitting station.
(c) The text.—This consists of plain language or Code groups. When Code groups are to be used they
should be preceded by the signal “YU”. Words of plain language may also be in the text, when the
signal includes names, places, etc. Receipt of each word or group is acknowledged by “T”.
(d) The ending.—It consists of the ending signal “AR” which is answered by “R”.
2. If the entire text is in plain language the same procedure is to be followed. The call and identity may be omitted when two stations have established communications and have already exchanged signals.
3. A list of procedure signals appears in Chapter 1, Section 10, Pages 19 and 20. Although the use of these signals is self-explanatory, the following notes might be found useful:
(a) The General call signal (or call for unknown station) “AA AA AA” etc., is made to attract attention when wishing to signal to all stations within visual signaling distance or to a station whose name or identity signal is not known. The call is continued until the station addressed answers.
(b) The Answering signal “TTTT” etc., is made to answer the call and it is to be continued until the transmitting station ceases to make the call. The transmission starts with the “DE” followed by the name or identity signal of the transmitting station.
(c) The letter “T” is used to indicate the receipt of each word or group.
(d) The Erase signal “EEEEEE” etc., is used to indicate that the last group or word was signaled incor-
rectly. It is to be answered with the erase signal. When answered, the transmitting station will repeat the last word or group which was correctly signaled and then proceed with the remainder of the trans- mission.
(e) The Repeat signal “RPT” is to be used as follows:
(i) by the transmitting station to indicate that it is going to repeat (“I repeat”). If such a repetition does
not follow immediately after “RPT”, the signal should be interpreted as a request to the receiving
station to repeat the signal received (“Repeat what you have received”);
(ii) by the receiving station to request for a repetition of the signal transmitted (“Repeat what you have
sent”).
(iii)The Special Repetition signals “AA”, “AB”, “WA”, “WB”, and “BN” are made by the receiving
station as appropriate. In each case they are made immediately after the repeat signal “RPT”. Examples:
“RPT AB KL”—“Repeat all before group KL”.
“RPT BN 'boats' 'survivors' ”—“Repeat all between words 'boats' and 'survivors' ”.
If a signal is not understood, or, when decoded, it is not intelligible, the repeat signal is not used. The receiving station must then make the appropriate signal from the Code, e.g., “Your signal has been received but not understood”.
(f) A correctly received repetition is acknowledged by the signal “OK”. The same signal may be used as an affirmative answer to a question (“It is correct”).

SECTION 6.—FLASHING LIGHT SIGNALING
(g) The Ending signal “AR” is used in all cases to indicate the end of a signal or the end of the trans- mission. The receiving station answers with the signal “R” = “Received” or “I have received your last signal”.
(h) The transmitting station makes the signal “CS” when requesting the name or identity signal of the receiving station.
(i) TheWaitingsignalorPeriodsignal“AS”istobeusedasfollows:
(i) When made independently or after the end of a signal it indicates that the other station must wait
for further communications (waiting signal).
(ii) When it is inserted between groups it serves to separate them (period signal) to avoid confusion.
(j) The signal “C” should be used to indicate an affirmative statement or an affirmative reply to an in- terrogative signal; the signal “RQ” should be used to indicate a question. For a negative reply to an interrogative signal or for a negative statement, the signal “N” should be used in visual or sound sig- naling and the signal “NO” should be used for voice or radio transmission.
(k) When the signals “N” or “NO”, and “RQ” are used to change an affirmative signal into a negative statement or into a question, respectively, they should be transmitted after the main signal. Examples:
“CY N” (or “NO” as appropriate) = “(Boat(s) is(are) not coming to you.” “CW RQ” = “Is boat/raft on board?”
The signals “C”, “N” or “NO”, and “RQ” cannot be used in conjunction with single-letter signals.
The requirement for signalling by light at sea is as follows:-
Please note that the STCW Code, Section A-II/1 states the mandatory minimum requirements for certification of officers in charge of a navigational watch on ships of 500 gross tonnage or more.
Every candidate for certification shall be required to demonstrate the competence to undertake, at the operational level, the tasks, duties, and responsibilities listed in column 1 of table A-II/1 of the STCW Code.
One of those competence is to Transmit and Receive information by visual signalling.
A knowledge, understanding and proficiency requires the ability to transmit and receive, by Morse light, distress signal SOS as specified in Annex IV of the International Regulations for Preventing Collisions at Sea, 1972, as amended, and appendix 1 of the International Code of Signals, and visual signalling of single letter signals as also specified in the International Code of Signals.
MCA approved training Colleges for the HNC programme have also an MCA approved examiner for the signal’s exams.
MCA Signal exam is split into 4 steps as follow:-
- Receive Morse by light – 20 letters. A group of letters and numbers is sent as a block.
- Transmit Morse. Students must be able to transmit a block of Morse code – 10 letters.
- Flags. Students to do a test on flags. Know what they are and their single letter meaning.
- General. Code and decode using INTERNATIONAL CODE OF SIGNALS (INTERCO) BOOK.
General Knowledge will be oral assessment.
I hope that the above information has addressed your query.

Wrong way waterfall 2018

Ice Climbing on the North Yorkshire Moors 2018
Time to head up to Great Fryup Head. There are extensive ice falls at the head of the dale on the west, but there are also a small number of routes right at the head of the dale between Yew Grain Scar and the George Gap Causeway. NZ 715018. If snow permits it is possible to access these from the Cut Road path at Trough House to the west, or where it joins the Lealhom to Rosedale road at 729028. Alternately park at opposite the outdoor centre in Great Fryup Dale and walk up.
Just to the east of the George Gap Causeway are three or four routes. The one on the left is probably around 15 to 20 ft in height. Ice axes are on the ice. Probably grade III. There's an excellent belay at the top - a large wooden stake securing a game keepers trap.
The largest of the waterfalls is this longish slide which is probably around the 50ft mark, with an easy angled extension continuing out of view below. There's also a little bit of mixed climbing to the immediate left in the picture.. If you are walking in from the dale this is a pretty obvious feature.
A mixed route probably grade ii/iii
The Smear. This feature was the result of a change in stream drainage a few years ago. The brown stain is the result of it flowing off ironstone strata. I've often wondered if it would freeze up, but it obviously needs slightly colder temperatures than the -4c we've been having. However there's still enough for a little sport.
