    Notice Date: July 19, 2019 To: General Authorities; General Officers; Area Seventies; and the following leaders in the United States and Canada: Stake, Mission, and District Presidents; Bishops and Branch Presidents; Members of Stake and Ward Councils From: Priesthood and Family Department (1-801-240-2134) Subject: For the Strength of Youth (FSY) Conferences in the United States and Canada As part of the Children and Youth effort announced on May 8, 2018, the Church will begin holding For the Strength of Youth (FSY) conferences in the United States and Canada. These conferences have been held outside the U.S. and Canada for many years and have proven to be a strength to youth and also to the young single adults who serve as counselors. See the attached description of FSY conferences for more information. Beginning in 2021 and 2022, all stakes in the U.S. and Canada will participate in FSY conferences every other year. During 2020, a smaller number of FSY conferences will be held at locations in the U.S. and Canada to prepare for full implementation. Attached is the list of stakes participating in 2020. If your stake has been selected to participate in FSY in 2020, please do not plan treks or youth conferences to be held during that year. Young Women and Young Men camps may be held annually, as usual. If your stake has been selected but you believe your stake has an exceptional circumstance and cannot participate in FSY in 2020, please contact your Area Seventy. Dates, locations, financing arrangements, and other information, such as the calling of young single adults as counselors, will be shared at a later date.

    Originalveröffentlichung in: H.F.J. Horstmanshoff- H.W. Singor- F.T. van Straten - J.H.M. Strubbe (eds.), Kykeon. Studies in Honour of H.S. Versnel, Leiden-Boston-Cologne: Brill 2002, S. 23-48 RITUAL DYNAMICS: THE BOIOTIAN FESTIVAL OF THE DAIDALA ANGELOS CHANIOTIS 1. Sources and puzzles In Turkish folkore Nasreddin Hoca is a representative of populär wisdom; his stories are well-known in Greece as well. One of them goes as follows: Nasreddin Hoca had been appointed as a judge in a dispute between two men. After the plaintiff had presented his case, Nasreddin Hoca looked at him and said: 'You are right'. Then it was the defendant's turn to present his argument and, again, Hoca's response was the same: 'You are right'. Thereupon one of the on- lookers at the trial turned to Hoca and said: 'You are the judge; you have to pass a judgment now'. Hoca looked at him calmly and an- swered: 'You are right, too'. Whenever I heard this story as a child, I laughed, but at the same time I was puzzled about its meaning. I still am, but I can not help thinking of this story whenever I read different interpretations of the same Greek festival. Of course, not everyone is right, but there is hardly any study which does not offer a new interesting insight. I also could not help thinking of Hoca's story again, when I read the jacket of the second volume of the Inconsistencies in Greek and Roman Religion. There, Henk Versnel expresses his conviction 'that the three approaches to religion known as "sub- stantivistic", functionalist and cultural-symbolic respectively, need not be mutually exclusive.' If I have chosen such a puzzling festival as the Daidala for this paper in honor of Henk Versnel, it is because I think that it pre- sents an interesting case of a ritual, in the study of which different interpretative approaches are not mutually exclusive or contradic- tory, but complementary.

    •••••a••• ••••a••••aa•a COLORADO Historical Background Study By BENJAMIN LEVY DIVISION OF HISTORY Office of Areheology and Historic Preservation October 15, 1968 National Park Service B&WScans U.S. Department of the Interior ..S·fb·~~ FOREIDRD The object of th.is study is to provide the historical data necessary :fOJ: the proper development of a Master Plan for Curecanti Rec:ceation Area, Colorado. This study, authorized by Resource Study Proposal (RSP) CURE-H-1, seeks to identi:fy historical resources and historic sites lo­ cated within or closely associated with the recreation area. Such an undertaking will enable master planning teams to consider the use o:f historical data in interpre­ tive and development programs and provide £or the protection 0£ historic sites and structures. Ideally, thE! background study ought to precede the master plan team's field investigation. The urgency 0£ the Curecanti plan r1equired this investigation to be undertaken immediately at the beginning of the current :fiscal year and compelled it to be done while the team was in the field. Hopefully, this report will have found its way into the team's hands prior to their completion report. This report does not pretend to be a detailed or de­ £ini tive study of the history 0£ the Curecanti area. The urgency of the c:all of this document and the limited time assigned for its preparation permit little more than the examination of secondary sources, although little i published mateI'ial exists on the history ox that stretch of the Gunnison River from Montrose to Gunnison city.

    Separating Fact from Fiction in the Aiolian Migration

    hesperia yy (2008) SEPARATING FACT Pages399-430 FROM FICTION IN THE AIOLIAN MIGRATION ABSTRACT Iron Age settlementsin the northeastAegean are usuallyattributed to Aioliancolonists who journeyed across the Aegean from mainland Greece. This articlereviews the literary accounts of the migration and presentsthe relevantarchaeological evidence, with a focuson newmaterial from Troy. No onearea played a dominantrole in colonizing Aiolis, nor is sucha widespread colonizationsupported by the archaeologicalrecord. But the aggressive promotionof migrationaccounts after the PersianWars provedmutually beneficialto bothsides of theAegean and justified the composition of the Delian League. Scholarlyassessments of habitation in thenortheast Aegean during the EarlyIron Age are remarkably consistent: most settlements are attributed toAiolian colonists who had journeyed across the Aegean from Thessaly, Boiotia,Akhaia, or a combinationof all three.1There is no uniformityin theancient sources that deal with the migration, although Orestes and his descendantsare named as theleaders in mostaccounts, and are credited withfounding colonies over a broadgeographic area, including Lesbos, Tenedos,the western and southerncoasts of theTroad, and theregion betweenthe bays of Adramyttion and Smyrna(Fig. 1).

    final environmental statement wild and scenic river study september 1979 GUNNISON RIVER COLORADO SPECIAL NOTE This environmental statement was initiated by the Bureau of Outdoor Recreation (BOR) and the Colorado Department of Natural Resources in January, 1976. On January 30, 1978, a reorganization within the U.S. Department of the Interior resulted in BOR being restructured and renamed the Heritage Conservation and Recreation Service (HCRS). On March 27, 1978, study responsibility was transferred from HCRS to the National Park Service. The draft environmental statement was prepared by HCRS and cleared by the U.S. Department of the Interior prior to March 27, 1978. Final revisions and publication of both the draft environmental statement, as well as this document have been the responstbility of the National Park Service.

C.; Callender, J. F.; [eds.], New Mexico Geological Society 32nd Annual Fall Field Conference Guidebook, 337 p. This is one of many related papers that were included in the 1981 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

    "On the Relations of Canaanite Exploration to Pre-Historic Classic

    176 ON THE RELATIONS OF CANAANITE EXPLORATION These inecriptions, and the bas-reliefs on the monument called Kamna Hurmill, in Crelo-Syria, near the source of the Orontes, and possibly of the same pe1·iod, are an enigma, as yet, to the most learned Orientaliots. It is to be hoped, however, now that attention is again called to the subject, that the clue may be found that shall unlock their meaning, and that Northern 8yI"ia will be no longer overlooked by tho explorer. DISCOVERY AT THE l\IOSQUE EL AKS.A, JERUSALEM.-llo A DISCOVERY of considerable interest has been made in this :Mosque by the Rev. J. Neil, who has only recently gone to Jerusalem for the Society for the Conversion of the Jews. "In the Mosque of El Aksa," he writes, "you will remember that there is a long plain room opening out at the south-east angle, called the Mosque of Omar, in which the only object of interest whatever is a recess supported by two twisted pillars, and called the Mihrab, or Praying-place of Omar. You may, perhaps, remember that the pillars on each side of this recess, of Solomonic twisted pattern and polished marble, appear to have been turned upside down, and to have their capitals of greyish stone in broken leaf-like patterns below. On vi~iting this the day before yesterday, July 5th, I discovered that a great part of the yellowish plaster had been removed from the top of these pillars, and that rich grotesquely carved capitals were exposed to view in an admirable state of preserva­ tion.
