Thrypti

Thrypti (Θρυπτή) is a mountain range in Lasithi in eastern Crete, Greece. It trends to the northeast from Ierapetra in the southwest in the direction of Sitia. However, it only goes half-way in that direction. The rest of the distance is completed by the distinct Ornon mountains, separated from the Thrypti by the Bebonas river valley, and the lower Western Siteia Foothills covering the space between the Ornon range and Sitia itself. The highest peak of Thrypti is Afentis, which is 1,476 m amsl. The three ranges constitute the West Sitia Mountains.

Geography
The Thrypti mountains are virtually 100% under the municipality of Ierapetra in Lasithi regional unit. The NE border of Ierapetra is so irregular that some small pockets of Thrypti might inadvertently be in neighboring Siteia municipality. Certainly the Sitia Mountains include ranges from both municipalities.

The Thripti mountains run diagonally SW from the southern coast at the city of Ierapetra (where they are not much in evidence) to the border of Sitia at Mirabello Bay, which is another reason why they alone are not the Sitia mountains. They are not even in Sitia. The Bebonas valley cannot serve as a border near the coast, as it only descends from its origin in the pre-existing mountains. The distance from Ierapetra to that valley is about 20 km, which can be taken as an approximate length of the mountains. The maximum width perpendicular to a representative length is up to about 9 km, but of course the width varies from a few km near Ierapetra.

The mountains are a massif, seen from outside the massif as a wall of mountains. On top the massif are the montane slopes and plateaus of low enough inclination to support pastures, some agriculture or dendriculture, and villages. It is too dry at those altitudes for much greenery; a bare rocky slope is the norm. The canyons, or gorges, are cut deeply into the edges of the massif by runoff from above, a process facilitated by the softness and solubility of limestone. Caves and deep cuts abound.

West side
One method of defining the borders of the Thripti massif is to follow the wall around its periphery. The terrain offers a good starting point in Vainia, a settlement of Ierapetra to its NE. The village is noted for Vainia Tower (35.02574°N, 25.78031°W), built by the Venetians 4.55 km from the city center at an elevation of 160 m. This landmark comes the closest of any to being the SW corner of the massif. It looks over flat farmland divided into plots all the way to the city. Above it looms Skouros peak, 440 m, and above that (35.066°N, 25.84107°W} Katalymata peak, 802 m.



Heading north on Route 20 (ΕΠ 20) at the foot of the massif one arrives at Plakoura, where Route 20A branches to the east toward Ha Gorge; otherwise, Route 20 does not approach it. The gorge is at the bottom of a valley flanked by Koufota, 880 m, to the south and Papoura, 990 m, to the north. Through the bottom of the gorge is only a hiking trail, considered dangerous, but 20A bypasses it, climbing in hairpin turns across the upper slopes of Koufota, to arrive at Thrypti plateau at the 722 m contour line, where the original Thrypti village is located (35.09119°N, 25.86335°W) under the high point of the range, Afentis, which reaches to 1476 m to the south. Springs in Thrypti feed a stream that plunges into the chasm at Mastoras waterfall.



Route 20 meanwhile merges into the coastal Route 90, which heading NE arrives at Kavousi, a city at the mouth of a larger valley dividing west Papouras from Kapsos, max elevation 997 m, to the north. The valley, called Havgas Gorge, is caused by the Kavousi river, which drains westward from the slopes of Spathi, 1177 m near Melisses, exits the massif at Kavousi, turns northward, and reaches Mirabello Bay at Tholos. Waters come from many tributaries within the gorge, which is extensive, including Mesona Gorge, which conducts water from the slopes of Afentis northward to intersect Havgas Gorge. As one might suspect, the terrain of Havgas permits a single winding road, characterized by numerous hairpin turns, to pass through it on the slopes above the river, going over the pass at its source to Bebonas. The pass is east of Melisses. It goes between Spathi and Kleros, elevation 1331 m, and serves as a source for the Bebonas River. It flows eastward, defining the border between Thripti and the Ornon Mountains.

North side
One might expect that all the peaks north of the Kabousi-Bebonas line would be the Ornon range, but this is not the case. Kapsas, which is about 4.77 km long SW-NE and 1.91 km wide transversely, is counted as Thrypti by some sources. Geographically, it forms the NW corner of the massif. Other sources count it as part of the Ornon range. The answer to the mystery is geopolitical.

Route 90A encloses the north of Kapsos forming a big bend from Kavousi on the west to Lastros on the east, located near the source of a S-N draining valley with Kapsos on its left and Tsigouni Gorge on its right. The border between Demos Ierapetras and Demos Siteias, however, proceeding N-S from the bay, cutting 90A, runs along the west side of the Kapsos ridge; i.e., it divides the mountain. South of Lastos it veers east to cut Spathi similarly on its upper north flank and also cuts the mountains on the north flank of the Bebonas Valley. This border is the traditional line of demarcation for the two ranges; i.e., half of Kapsos is Thrypti, and the other half Ornon, etc.
