From Matapalo westwai-d toward Burica Poiut we see the first exten- 

 sive stretch of swamp level along this coast. This, together with

 Peninsula of Salsipuedes.

other topographic features of the region, is well illustrated upon the 

 hydrographic chart of the Gulf of _ 



Dulce. This swamp level is identical 

 in character with the Isthmian fea- 

 tures, and from its aspect I could con- 

 sider it to be a littoral sea margin of 

 recent elevation. Back of this swamp 

 with its bordering lagoon are the high 

 hills of the Dulce peninsula, rising to 

 1,600 feet in height. 



Subsequently we passed Point Salsi- 

 puedes, with its small outlying rocky 



islets as if they had been recently separated from the mainland. One 

 of these, known as Cucovada Bock, has a mushroom form, the waves 



having eroded its basal por- 

 tion so that only a small 

 pedestal is preserved as a 

 central support to the over- 

 hanging ledges of the sum- 

 mit, which is of the Panama 

 peneplain level. Similar 

 outlying islands are seen off 

 Lorena Point. Just before 

 reaching the latter we pass 

 many miles of vertical wave- 

 cut bluffs, the sea appar- 

 ently encroaching directly on the mountain country, without the 

 intervention of the lower levels. At one point a beautiful waterfall 

 can be seen dropping from the summit of the bluff into the sea.
