  We present Wind spacecraft observations of ion distributions showing
field-aligned beams (FABs) and large-amplitude magnetic fluctuations composed
of a series of shocklets and short large-amplitude magnetic structures (SLAMS).
We show that the SLAMS are acting like a local quasi-perpendicular shock
reflecting ions to produce the FABs. Previous FAB observations reported the
source as the quasi-perpendicular bow shock. The SLAMS exhibit a foot-like
magnetic enhancement with a leading magnetosonic whistler train, consistent
with previous observations. The FABs are found to have T_b ~ 80-850 eV,
V_b/V_sw ~ 1-2, T_{b,perp}/T{b,para} ~ 1-10, and n_b/n_i ~ 0.2-14%. Strong ion
and electron heating are observed within the series of shocklets and SLAMS
increasing by factors \geq 5 and \geq 3, respectively. Both the core and halo
electron components show strong perpendicular heating inside the feature.
