FIG 232. Looking northwards over the Great Ouse and Bedford (Fig. 231, b5 ; see Fig.
240 for a better idea of the location). (Copyright Aerofilms)
The photograph over Bedford (Fig. 232) shows a relatively wide reach of the
Great Ouse, but this is the result of the raising of the local river level by engineering
structures. The medieval town lay north of the river, but new roads have been created
to allow for modern traffic. More recent development has greatly extended the city, and
has created radial patterns of development north and south of the Great Ouse.
Considerably downstream from Bedford at St Ives ( b6 ; Fig. 233), the medieval
markets and lanes are beautifully preserved, as well as the ancient bridge incorporating
a chapel. In the further distance the numerous lakes are the result of flooding gravel
pits that mark the deposits of the ancestral Great Ouse, which deposited large quantities
of gravel at the end of the last (Devensian) glaciation.
