Overview
In the northern side of Monte Rosa group the main watershed ridge turns to the East dividing the Valle Anzasca (S - Italy) from the Sass valley (N - Switzerland).
On this ridge, beginning with the Roffel summits (W) and ending at Monte Moro and Joderhorn (E) a summit looks very smart : the Seewjinenhorn : 3204m.
The huge rocky bulwarks that make the N border of the Valle Anzasca hide this summit whose shape can be appreciated only from the other side of the Valle Anzasca (S) or from the slopes near the Passo di Monte Moro.
From its summit a long spur (about 1000 m of difference in elevation) comes down toward Macugnaga dividing the basin of Roffel (W) from the Moro's one (E).
Its N (iced) low slopes are crossed by the famous route
"Sentiero del Camosci" (Chamois path) that joins the Passo di Monte Moro to the Rifugio Sella (Weissthor)
Getting There
the access to this mountain can be done both from Italy and Switzerland
Italy
From the highway of Simplon Pass exit Piedimulera
Follow for Macugnaga
Switzerland
From the highway of Wallis exit Saas
Follow for Saas Almagell and up to Mattmark dam
Route
the best, and I think, the only route normally used to get this summit, follows the E ridge starting from the "Bocchetta di Galkerne" (pass W of Monte Moro) that can be easily reached using a path partially digged into the rock and starting from Passo di Monte Moro.
From this point follow at best the ridge, leaving down the tracks of the Sentiero dei Camosci that goes along the glacier.
The route is easy but a rope and an iceaxe can be useful.
(I climbed it some 40 years ago leading my girlfriend (now wife) and I can remember it took less than 2 hours from Passo di Monte Moro : a very fine way to spend a fine weather day in Macugnaga, you can climb it directly from the bottom of the valley using the cablecar.
I heard about a long rocky route that follows the entire S spur with difficulties up to 4° UIAA on normally good rock
