or Yablonoy Mountains, a chain in Siberia, extending for about 3000 miles in a direction for the most part N.E. from the Altai range, parallel to the shores of the sea of Ochotsk, as far as Behring Strait. This chain sends out numerous smaller branches, but it is more remarkable for length than for altitude. South of 55° N. Lat., the mountains are densely wooded; from that point as far north as 63°, they gradually become more and more bare, and beyond the latter point they are quite covered with snow. Many considerable rivers take their rise in the Stanovoi Mountains.
