The Ionian Sea (Modern Greek: Ιόνιο Πέλαγος, romanized: Iónio Pélagos, IPA: [iˈoni.o ˈpelaɣos]; Italian: Mar Ionio or Mar Jonio, IPA: [mar ˈjɔːnjo]; Albanian: Deti Jon, IPA: [ˈdɛti ˈjɔn]) is an elongated bay of the Mediterranean Sea. It is connected to the Adriatic Sea to the north, and is bounded by Southern Italy, including Basilicata, Calabria, Sicily, and the Salento peninsula to the west, southern Albania (and western Apulia, Italy) to the north, and the west coast of Greece, including the Peloponnese.
- Klickitat River (Wikipedia)
The Klickitat River is a tributary of the Columbia River, nearly 96 miles (154 km) long, in south-central Washington in the United States. It drains a rugged plateau area on the eastern side of the Cascade Range northeast of Portland, Oregon. In 1986, 10 miles (16 km) of the river were designated Wild and Scenic from the confluence with Wheeler Creek, near the town of Pitt, to the confluence with the Columbia River.
