H I 21 cm channel maps of the high-latitude (25° ≤ b ≤ 47°) part of the Loop I from the GASS survey. The H I 21 cm line area is integrated in ∆v = 0.8 km s^-1 channels centered at v_LSR = -3.3 km s^-1 v_LSR = -0.8 km s^-1 v_LSR = 3.3 km s^-1 in the left, center, and right image, respectively. The positions of the L1780, Zebra1 nebula and DIR316+39 are marked. A Galactic coordinate grid is overlaid.
