Самый древний – в низовьях р. Евъваям близ побережья Берингова моря, его морены характеризуются плохой сохранностью и значительно эродированы. В среднем течении выделяется хорошо выраженный в рельефе комплекс из трех более молодых и лучше сохранившихся моренных гряд (45, 62–72 и 87–95 м над у. м.), на которых сформировался маломощный почвенный покров. Самые молодые морены встречены в верховьях долины р. Евъваям на отметках 240–320 м над у. м., где они образуют продольные гряды – “языки”. Степень сохранности, морфология и размеры исследованного ледникового комплекса с учетом опубликованных данных по сопредельным районам указывают, что оледенение территории имело горно-долинный характер и максимальных размеров ледник, видимо, достигал в начале позднего плейстоцена, когда он выходил за пределы долины р. Евъваям к побережью. Морены в центральной части долины и в ее верховьях сформированы ледниками конца позднего плейстоцена, которые имели меньший масштаб. Область их питания в этот период ограничивалась серией ледниковых цирков и каров центральной части Пылгинского хребта. В настоящее время в цирках на отметках от 410 м до 720 м над у. м. также наблюдаются небольшие ледники, продолжающие формировать современные морены.</p></abstract><trans-abstract xml:lang="en"><p>Based on the interpretation of satellite images and field observations, three moraines of different ages and morphology were identified in the valley of Ev’vayam River. The oldest, poorly preserved and significantly eroded moraines are located in the lower reaches of the Ev’vayam River near the Bering Sea coast. A well expressed in relief complex of younger moraines consisting of three better-preserved moraine ridges (45, 62–72 and 87–95 m a. s. l.) with thin soil cover is distinguished in the middle reaches of Ev’vayam River. The youngest moraines are found in the upper reaches of the Ev’vayam River Valley at elevations of 240–320 m a. s. l., where they form longitudinal ridges, or “tongues”. Based on the preservation degree, morphology and size of the investigated glacial complex, and published data on adjacent areas, the glaciation of the territory had a mountain-valley character. The glacier apparently reached its maximum size at the beginning of the Late Pleistocene, when it moved beyond the valley of the Ev’vayam River to the coast. The moraines in the central part of the valley and in its upper reaches were formed by much smaller glaciers during the end of Late Pleistocene. The recharge area of glaciers during this period was limited to a series of glacial cirques and kars in the central part of Pylgynskiy Range. Currently, small glaciers are present in cirques at elevations from 410 m to 720 m a. s. l., and continue to form modern moraines.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оледенение Северо-Восточной Азии</kwd><kwd>плейстоцен</kwd><kwd>палеогеография</kwd><kwd>четвертичные оледенения</kwd><kwd>морены</kwd></kwd-group><kwd-group xml:lang="en"><kwd>glaciation of Northeast Asia</kwd><kwd>Pleistocene</kwd><kwd>paleogeography</kwd><kwd>Quaternary glaciations</kwd><kwd>moraines</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Полевые работы проводились в рамках темы госзадания ИГ РАН № FMGE-2019-0004; работа со снимками, обработка полевых материалов и обобщение результатов выполнены при поддержке гранта РНФ № 21-17-00054</funding-statement><funding-statement xml:lang="en">The fieldwork was conducted within the framework of the state task No. FMGE-2019-0004 of the IG RAS; work with images, processing of field materials, and summarizing the results was supported by the Russian Science Foundation Project No. 21-17-00054</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ананьев Г.С., Ананьева Э.Г., Бодрова О.В., Пахомов А.Ю.
